Auction Basics

Learn more about our platform and how our auction system works.

Why do auctions extend at the end?

If a bid is placed in the last 7 minutes of an auction, the auction end time will extend for an additional 3 minutes. This is called "Popcorn Bidding" and gives all bidders an equal chance of winning an auction if a last minute bid is placed. Popcorn bidding simulates a live auction and prevents other bidders from "sniping" an auction at the last second.

What if I have more questions about an auction?

All of the information about a specific listing is available on the auction page.

Supply Demy auction pages have a button called “Ask Seller A Question” where you can request more information from the seller.

Don’t bid on an auction if you have unanswered questions or are unsure about the purchase.

Lack of information is not a valid reason for cancelling a bid or order.

If you have additional questions, you may reach out to Customer Support.

Where are you located? Who sells the merchandise on the site?

The auctions on Supplydemy.com are from both small and large businesses liquidating their excess inventory. The auction page and description displays the location of the merchandise.

SupplyDemy does not own any of the merchandise listed on the site. We are a marketplace connecting buyers and sellers.

What condition is the merchandise in? Is it all new?

The condition of the merchandise being sold varies between auctions, and can be anything from new in box to salvage condition. Please view the auction page for listing information and visit our "Conditions" page for more information on each condition type.

When are new auctions posted?

New auctions are posted throughout the day. There is no set time for all auctions to start.

Most auctions run for 48 hours and are posted Monday through Friday. Auctions typically end between 10 am and 4 pm PST (1 pm - 7 pm EST).

You can find auction close time details on any auction listing.

Are the images on the auction actual pictures of the merchandise?

Please be advised that this will vary from auction to auction. Some auctions feature actual images of the products sold, others only display stock images.

What does the retail price published on the auction mean?

The retail price listed on the auction is also known as the original retail price. It is the highest possible price at which the product was offered when it was new to market.

SupplyDemy does not verify original retail values submitted by sellers. It is the buyer’s responsibility to research any and all current retail prices and values before placing their bid.
