We have a grocery store nearby that just got this machine that will buy your unwanted gift cards from you. I'm sure it doesn't give you full value for them because they have to make a little something for themselves, but it's still a good way to get rid of those cards to Aeropostale you'll never use and get cash instead. Then you could convert that cash into awesome toys instead of crappy shirts with a store's name on them.
Personally, I would buy these exclusive Monster Worship toys from Foe Gallery. They are part of the Mysterium show that is currently on exhibit, but these guys are ready to ship to you right now. Both are cast in clear red vinyl and extremely limited so get to ordering son! Pick em up from http://www.shopfoe.com/.
