We’re pleased to announce the launch of our newest marketplace for mobile devices: Select Mobile Auctions. The B2B marketplace for a large OEM will offer qualified U.S.-based buyers bulk quantities of smartphones from various manufacturers.

The devices available on the marketplace have been previously used and will come from various sources including customer trade-ins and returns; device conditions range from Grade A to Grade C and will be noted on each auction lot.

"I feel so confident shopping and bidding on items knowing that I am going to get what I paid for. And if not, there’s a killer customer service team that’s going to make sure everything’s alright in the end. That’s huge. It’s hard to take that risk when you’re first starting out."
