So here's something I just got into. On the counter at DD they usually have a spinning kiosk with various gift cards, many feature designs with local sports teams or current promos, like Captain America. It's cheap - FREE!
I'm pretty much looking for any I don't have. I just started this so my "have" list is very small. But you can help fix that.
Have:
Boston Celtics
Boston Red Sox
Captain America
Philadelphia Eagles
University of Delaware
Available to trade:
Captain America
