Cardpool and get cash for them?
I just sold an old gift card that I haven't used in the 7 years I've had it. It was super quick and easy! The gift card was worth $46 and I received $41 (I chose Amazon gift card as payment, which gave 6% more, but you can also get a check).
Plus, you can buy discounted gift cards at Cardpool as well!
If you sign up HERE you can get a $5 credit to start with!
This is a great way to turn those gift cards that have been sitting around into CASH!
