I've sold to them 3x, all within the past week. They ask for GC number and verification code and verify the funds available. Once they've verified the funds, they email you to let you know a check is on the way. I received the check a few days later. They do require a credit card be put on the account in the event the gift cards have been drained before the purchaser uses them, but I'm not going to do that so all should be well. They also caution sellers to shred the GC so they don't "accidentally" use them.
