I love gift cards. There's just something awesome about walking into, say, Starbucks, and feeling like I'm getting my decaf skinny mocha Frappucino for free.
Same goes for shopping on iTunes. You just gotta love buying an album, e-book, movie, or the like without spending "real money." If I get nothing but gift cards for all my remaining birthdays, Father's Days, Chanukah days, and other gift-worthy occasions, I'll be a happy fellow.
