Some items may be sealed in original factory packaging. However, many are not new. Our auctioned items are a variety of returns in various conditions.

Power cords are not guaranteed. (We may have a cord/charger for you to test the item to make certain it charges/powers on, however, we do not guarantee that we will have your cord.) It would be in your best interest to bring a cord with you on pick-up day. You will need to purchase the cord/chargers from a retail store. This is not our responsibility.

Our auction has contracts in place with the largest retailers. We help companies liquidate their returns while giving our customers a great deal.

All orders that are not picked up will be forfeited along with payment. If two unpaid invoices are active on an account your account will be disabled until the balance is settled.

We expect our customers to do their homework prior to making their bids. We currently don’t have the infrastructure or manpower to take back a large number of returns based on customers’ mistakes. Once a bid has been placed, you are promising to pay for the item, otherwise, someone else could have won the item. We MUST make all bids final to keep the auction running smoothly on a weekly basis for all of our customers.

All Items that are out of the box are being sold PHYSICALLY AS IS. We will try to take several pictures of the item. Please make sure to look at all pictures before bidding.

We are an auction house that sells new and used items. The majority of our items are in great working condition but some may have imperfections. We are NOT responsible for dents, scratches, blemishes, discoloration, missing parts & accessories.

All items not picked up in the allotted time (pick-up days are Sunday and Monday following the auction) 

These products are guaranteed to be brand new. Unlike the auction which comes in a variety of returned e-commerce products.
