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.)

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.
