AuctionNinja and the User acknowledge and agree that (i) AuctionNinja owns all right, title, and interest in and to the AuctionNinja Platform, any modifications or customizations thereof, and any and all intellectual property or proprietary rights anywhere in the world, irrespective of whether such rights arise under U.S. or foreign intellectual property, unfair competition or trade secret laws (collectively, "Proprietary Rights"), in or to any of the foregoing and (ii) subject to AuctionNinja's underlying ownership of the AuctionNinja Platform and the Proprietary Rights therein and thereto, the User owns all right, title, and interest in and to the User Material.

A. Definition. "Confidential Information" means (i) any information disclosed (directly or indirectly) by one party ("Disclosing Party") to the other party ("Receiving Party") pursuant to this Agreement that is in written, graphic, machine readable or other tangible form (including, without limitation, research, product plans, products, services, equipment, customers, markets, software, inventions, processes, designs, drawings, formulations, specifications, product configuration information, marketing and finance documents, prototypes, samples, data sets, and equipment), and or is (ii) information, including that communicated orally, which is otherwise reasonably expected to be treated in a confidential manner under the circumstances of disclosure under this Agreement or by the nature of the information itself.

B. Exceptions. Confidential Information shall not, however, include the User Material, or any information that: (i) was publicly known or made generally available without a duty of confidentiality prior to the time of disclosure by Disclosing Party to Receiving Party; (ii) becomes publicly known or made generally available without a duty of confidentiality after disclosure by Disclosing Party to Receiving Party through no wrongful action or inaction of Receiving Party; (iii) is in the rightful possession of Receiving Party without confidentiality obligations at the time of disclosure by Disclosing Party to Receiving Party as shown by Receiving Party's then-contemporaneous written files and records kept in the ordinary course of business; (iv) is obtained by Receiving Party from a third party without an accompanying duty of confidentiality and without a breach of such third party's obligations of confidentiality; or (v) is independently developed by Receiving Party without use of or reference to Disclosing Party's Confidential Information, as shown by written records and other competent evidence prepared contemporaneously with such independent development.

C. Non-Use and Non-Disclosure.

Each party agrees that the unauthorized use or disclosure of the other party's Confidential Information may cause irreparable injury to the party concerned. Accordingly, both parties agree that the remedy at law for any breach of this Section 7 may be inadequate and that the party suffering from the unauthorized use or disclosure shall be entitled to ex parte injunctive relief to prevent any such breach or the threat of such a breach.

E. Compelled Disclosure. If Receiving Party becomes legally compelled to disclose any Confidential Information, other than pursuant to a confidentiality agreement, Receiving Party will provide Disclosing Party prompt written notice, if legally permissible, and will use its best efforts to assist Disclosing Party in seeking a protective order or another appropriate remedy.

F. Return of Confidential Information.

This Terms of Use and Conditions works in conjunction with the Seller's Subscription Agreement, also known as the Software-as-a-Service Agreement.

In order to sell on the Site, AuctionNinja Sellers must agree to the all of the following: Terms of Use and Conditions, Privacy Policy, and Subscription Agreement.


All items are sold as-is, where-is. While AuctionNinja Sellers are expected to do their best to list any damage, repairs or restorations, the absence of these descriptions or conditions must not be taken to imply that the lot is in perfect condition. Most of the items sold by Sellers on the AuctionNinja platform are antique, vintage or used. You should expect signs of wear consistent with age. AuctionNinja Sellers often offer preview inspections for the sole purpose of allowing Buyers the opportunity for personal inspection before placing bids, but are not required to do so. Condition reports may also be available, depending on the Seller. If you have any doubts or questions about any lots being offered by Sellers, be sure to reach out directly to the AuctionNinja Seller BEFORE bidding. Seller contact information may be found on the individual auction landing page. All sales are final. No returns, credits or exchanges.


A buyer's premium (typically 18%, but may vary from one Seller to another) will be added to the hammer price in all auctions and will be charged along with the hammer prices and applicable sales tax to the credit or debit card you have on file with AuctionNinja within 24 hours of the auction end. Please review the terms of sale for each Seller before bidding.


All sales are subject to appropriate sales tax laws in the states where the sale is being held. Tax exempt Buyers must provide the appropriate state sales tax exemption certificate prior to the end of the sale. Upon receipt of such information by AuctionNinja, your future purchases will not be taxed. Tax resale forms can be submitted in your membership profile. Your profile name and address must be the same as your resale certificate.


Buyers must be very careful in placing bids, as once their amount is entered, it is NOT retractable. Buyers may increase their maximum bids at anytime. Any subsequent coordination for adjustment, cancellation, refund, etc. needs to be done directly between the Seller and Buyer, independent, separate and without involvement of AuctionNinja. AuctionNinja is NOT responsible for-and, will NOT perform-any corrective actions or adjustments.

By entering a bid amount in an auction and clicking on "Submit Bid," the Buyer commits to buying the listed item from the Seller if they end up becoming the winning bidder. Furthermore, AuctionNinja does NOT offer any sort or type of Buyer or Seller protection plans, programs, warranties and/or guarantees. AuctionNinja also does NOT offer any sort or type of price matching or best price programs and/or guarantees.

To initiate your ability to bid with AuctionNinja, an initial $1.00 pre-authorization transaction will appear on your statement. This pending transaction will not settle and will drop off after 5 -7 business days, depending on your card's issuing bank (American Express & Discover may take longer).

Successful Buyers must pick up their items at the designated sale location within the assigned time frame as stated in the sale details page. If you have any doubts about your ability to pick-up your auction winnings and the designated sale location during the designated times, DO NOT BID.

If after winning an item you determine you are unable to pick up your items during the scheduled removal times and dates, you must contact the individual AuctionNinja Seller within 24 hours prior of the scheduled pick-up date and the Seller will determine if alternate arrangements can be made. Arrangements will be at the sole discretion of the AuctionNinja Seller and may be subject to additional transport, labor and/or storage fees - payable directly to the Seller.

AuctionNinja is strictly a venue to facilitate successful transactions between Site Users (Buyers and Sellers), and currently does NOT provide any direct or physical shipping/delivery capability for Users. Buyers are strongly urged to completely read through and fully understand the Seller's shipping/delivery policy and/or terms of sale stated within the auction listing description, and contact the Seller directly for any further clarity and confirmation if anything is uncertain, ambiguous or unclear.

As a Seller, you are entirely responsible that the Buyer successfully and satisfactorily receives what they pay for. Each Seller is strongly recommended to develop and explicitly describe their shipping/delivery/distribution/pick-up policy on each and every one of their listings, along with available shipping/delivery carriers, options and service with associated costs, if applicable.


Any items not paid and / or not picked up during the specified pick up time in accordance with the Seller's Terms of Sale will be forfeited by the Buyer. AuctionNinja Sellers, at their sole discretion, may re-offer the items or donate them to a charity of the Seller's choosing. AuctionNinja reserves the right to report your account to collections for the combined total of the original invoice amount and any moving or disposal charges. Your membership with AuctionNinja will be revoked unless past due invoices and any additional charges are paid in full.


You agree not to sell, license, rent, modify, distribute, copy, reproduce, transmit, publicly display, publicly perform, publish, adept, edit or create derivative works from content (including imagery) or materials on the Site. Use of the content and materials for any purpose not expressly permitted in these Terms of Use and Conditions is prohibited. You may not decompile, reverse engineer, disassemble, or otherwise reduce the Site to a human-perceivable form, except and only to the extent that such activity is expressly permitted by applicable law, and in that case, only if you notify AuctionNinja in writing in advance. You may not copy, frame-set, enclose or otherwise distribute any part of the Site.


You will not hold AuctionNinja responsible for the actions or inactions of site Users, contents of their listings, items they list, nor their destruction of alleged fake and counterfeit items. You acknowledge that AuctionNinja is not a traditional "auctioneer" or "auction house." Instead, AuctionNinja is just a venue or bidding platform, which allows Sellers and Buyers the convenience to offer, sell, and buy practically anything, at anytime, from anywhere, in a variety of pricing formats and locations, such as, online auctions and online store formats. AuctionNinja is not involved in the actual transaction between site Users-the Buyers and the Sellers.

AuctionNinja has no control over and does NOT guarantee the quality, safety or legality of items advertised, the truth or accuracy of Users' content or listings, the ability of the Sellers to sell items, the ability of the Buyers to pay for items, or that the Buyer or the Seller will actually complete a transaction.

AuctionNinja does NOT transfer legal ownership of items from the Seller to the Buyer. Uniform Commercial Code (UCC) § 2-401(2) applies to the transfer of ownership between the Buyer and the Seller, unless the Buyer and the Seller agree otherwise. Accordingly, to the extent legally permitted, AuctionNinja excludes all implied warranties, terms and conditions. AuctionNinja is NOT liable for any loss of money, goodwill or reputation, or any special, indirect or consequential damages arising, directly or indirectly, out of your use of or your inability to use AuctionNinja's Site, services, and tools.

Some jurisdictions do not allow the disclaimer of warranties or exclusion of damages, so such disclaimers and exclusions may not apply to you. Regardless of the previous paragraphs, if AuctionNinja is found to be liable, AuctionNinja's liability to you or to any third party is limited to a maximum of the total fee, if any, paid to AuctionNinja only by you for the specific transaction(s) involved with the Buyer and the Seller. AuctionNinja is NOT responsible for any other costs, such as; but, not limited to, shipping, restocking, legal or indirect fees involved in and/or resulting from the specific transaction(s).


Refer to AuctionNinja’s PRIVACY POLICY.


AuctionNinja's online auction system features extended bidding (a.k.a. "soft close"). This feature is built into the coding of AuctionNinja and is fully automated. It is the closest way to mimic the actions of an auctioneer (during a live auction) in an online/automated format. To illustrate, during a live auction the auctioneer typically won't hammer at the first bid. The auctioneer gives bidders opportunities to increase their bids until he/she determines there is no further interest in the lot before hammering to the winning bidder. Therefore, AuctionNinja's automated system will automatically extend the closing time of a lot (auction item) whenever a new bid is placed within the last five minutes of its scheduled closing to allow other interested bidders an opportunity to increase their bid (if they wish to do so). This may occur multiple times on any given lot depending on bidder interest. Once all interest and bidding in a lot ceases, the clock will run out and the lot will close.
