It does make things a tad awkward, come Christmas morning. Gift cards are cool for, like, an office secret santa -- $10 gift limit, $10 card -- but a gift card isn't very useful for my family's annual tradition of reading your new books Christmas afternoon(or the other tradition of looking up if your new gifts are actually legal to own in Canada). So . . . one is fine, but it'd be annoying if everyone did it to you.
