Can I come by and view the items in person?

Sorry but No, in order to maintain a level and fair playing field for all bidders, no one is allowed to view the items before or during the auction. No exception.   If you feel that you cannot make a buying decision based solely on the pictures in the auction listing, please do not bid.  Everything is sold as-is, where-is and there are no refunds.

Does an American Girl doll fit in a large flat rate box?

Yes American Girl and most dolls of similar size will fit in a large flat rate box and can be shipped in-house.

What is a buyer's premium?

A buyer's premium is a percentage-based fee added to the winning hammer price. This helps cover the auctioneer’s expenses and administrative costs and off-sets credit card fees. Bidders may also be charged sales tax (depending on regulations of the individual state where the auction is held) on this additional fee.

Here’s an example ...
If you won an auction lot through Marketplace-Auctions with a 12% buyer’s premium and 6.25% Massachusetts state sales tax (the buyer’s premium is often taxed, but laws vary by state) here’s how it would work out:

Hammer Price


Buyer’s Premium (12%)


MA Sales Tax (6.25%)







What is an absolute auction?

An absolute auction is a sale without a reserve price, where the hammer price is awarded to the highest bidder regardless of the hammer price. For example, in an absolute auction, a wine refrigerator could hammer at $5 because there was only one bidder bidding on that lot in the absolute auction.

What is a reserve?

First off, let's define reserve price. A reserve price sets a minimum required bid for the item to be sold. In many traditional auctions, reserves are undisclosed (the bidders have no idea what the reserve price may be -- a blind reserve).

We at Marketplace-Auctions DO NOT put reserves on any items.  If the item opens at $5 and you are the only bidder, you will get the item for $5!


What is extended bidding?

Our Auction platform features extended bidding (a.k.a. "soft closing"). The Auction system will automatically extend the closing time of a lot (auction item) whenever a bid is placed within the last five minutes of its scheduled closing. This may occur multiple times on any given lot depending on the bidder interest in that lot. Once all interest and bidding in a lot ceases the clock will run out and the lot will close.

This is the fairest way to prevent “bid sniping” (someone submitting a high bid in the last seconds of any given lot’s closing in order to win said lot) and to give all bidders an opportunity to increase their bids if they wish. It is also the closest way to mimic a live, in-person auction, when the auctioneer gives bidders opportunities to increase their bids if someone jumps into the bidding at the last moment before hammering the winning bid. 

Sometimes I'm immediately outbid. Why?

Because all maximum bids are "masked" (hidden from other bidders), you do not know what any other bidder's maximum bid may be or when they placed it. Sometimes you will be outbid as soon as you enter your bid. This only occurs when another bidder had a higher maximum bid than yours already "on the board". Your bid set in motion BRG's automatic bidding system which raised the other buyer's bid above yours. The other bidder may have placed their max bid days, hours, or mere moments before you placed yours. 

However, if you place a bid and there are no competing bids against your bid, the system WILL NOT immediately go to your maximum bid. In fact, if you are the only bidder by the time the lot closes, you will win the lot for the lowest possible dollar amount (based on whatever the opening bid was for that item), not your max bid. So if you place a max bid of $25 on a lot with an opening bid of $1 and there are no other bidders vying for that lot, you will win it for $1. NOTE: This only happens when there are no competing bids.

Why was I outbid by an amount less than the next minimum increment?

Occasionally our bidders are outbid by an amount lower than the minimum bid increment (see bid increments in our Terms & Conditions). All bidders may place their max bid at anytime.  As a result, you may be outbid by what seems to be an incorrect increment.  The AuctionNinja system will not default to strict increments like a traditional auction if an "odd" maximum bid was left prior to meeting the bid price which would engage the next bid increment. 

For example, let's say you place your maximum bid of $100 on a painting but another buyer wins the lot for $101. As stated in the bidding increments, you know the next bid should have been $105, not $101. The system will accept the $101 bid because that max bid of $101 was placed before the auction got to that next increment level.

Here's how: It's 4 p.m. on closing day and the painting is currently at $15. At 5:10 p.m. you place a maximum bid of $100. There are a few bidders at play and so by the time 5:45 comes around, the current bid is at $78 with you as the highest bidder.  At 7:05 p.m. a new bidder joins in and places his maximum bid of $101. Since this new bidder's bid of $101 is above the minimum increment at the time she placed the bid, it is accepted by the system. Since there were no additional bids placed before the countdown clock ran out, the $101 bidder wins the lot because it is higher than your $100.

My max bid was the same as the winning bid (tie bid), yet someone else won it. Why?

In the case of a tie bid, the hammer will always fall to the first bidder. For example, the current bid is $50 (placed by someone else). What you don't know is that their max bid (which is masked from other bidders) is $200. You join the bidding and and place a maximum bid of $200 and are immediately outbid in favor of the other bidder. Even though two people have the same max bid, only one person can win the lot. That is automatically determined by bidding order -- the person who placed that maximum bid first.

Post Auction

Can I pay by cash or check at pick-up?

The only method of payment accepted is credit card via auto-debit at the close of the auction. This makes it easy for bidders to simply show-up at the designated location and pick-up their items. It also is safer and more secure for our auctioneers/sellers who, otherwise would be concerned about holding large sums of cash on hand.

Do you ship?

Yes please visit the shipping Services section of this website

I won an item in an auction, what now?

Within two hours of the close of the entire auction your credit card on file will be charged for the entire amount due (hammer price + sales tax + buyers premium). The charges are not processed until the entire auction closes. You will also receive a winning bidder email which will list your invoice (what item(s) you won, the hammer price, sales tax, and buyers premium) and all necessary pick-up instructions. Note the pick-up instructions are also always viewable on the auction landing page. Any questions about the auction results and/or pick-up instructions should be directed to the individual vendor/seller (details for the seller may be found on the auction landing page).

I won some items, where do I pick them up?

Please wait until the end of the auction.  You will receive the pick up address and then you can schedule a pick up time.


I am the winning bidder and now realize that I don’t want my items. That’s ok, right?

In short, no. No, it’s not ok. When you bid on any items in an auction, it’s a legally binding agreement to purchase the item(s) if you are the winning bidder. Once the auction closes, if you’re the high bidder, per the terms of use / bidder agreement, you are obligated to follow-through on your purchase. Auctions do not work like retail stores where you can return an item if you have “buyers remorse.” So you must be sure that you are able to uphold your end of the agreement before placing your bid(s). You must do your own "due-diligence" in researching the items you plan to bid on -- before bidding -- per the terms of bidding. Items are sold "AS-IS, WHERE-IS," meaning there are no guarantees, warrantees, etc. Reneging on your agreement as the winning bidder in any auction will result in the permanent revocation of your bidding privileges on the AuctionNinja platform.
