Gift Card exchange?

Anyone familiar with a trustworthy site for exchanging gift cards? I have a $50 Best Buy card I really don’t need and would like to swap it for an Amazon card since the online bookstore at doesn’t accept their gift cards and there are a couple programming books I want to get.

I’ve looked around sites like plasticjungle but I’m wondering if anyone has a recommendation before I end up doing something dumb.

A buddy of mine used plasticjungle. Worked fine.

Coolio, thanks Jose Liz. Your input adds validity to an otherwise completely unknown website asking for my money.

Sbarros rocks.

And I would just use E-bay.
