I've used Cardpool for a number of transactions throughout the years. As gifts during our wedding we received a number of Bed Bath & Beyond gift cards that we unloaded on Cardpool. The transaction was absolutely seamless. I also just sent in the Neiman Marcus gift card and everything went well (I've already received and deposited the check).

I have a number of Cardpool transactions coming down the pipe in the next couple of weeks as well.

My biggest fear with Cardpool is the actual mailing of the gift cards. If the cards get lost in the mail or stolen you're pretty much up the creek!
