Should i buy this.... for my teachers?

One year I had my kids give their teachers gift cards to a book store along with a book mark in a Christmas card. A few years later a couple of those teachers mentioned that it was a unique present. For a teacher to remember who gave them this years later made me happy. Teachers get a lot of mugs, candy, and"teacher" related knick knacks. These gift cards can be for only $5 but they'll think of you when they spend them.
