For me, Valentines day has never been about giving someone a present, or seeing who can buy their significant other the most expensive gift (my idiot friends used to do that all the time, the fools), but it's about showing those people I care about, just how much they mean to me. Even if it's only a simple hug, or kiss, or a flower I've stolen from the schools' gardens, they'll know I've thought of them, and that's what counts.
I don't buy into the commercial holdiays (except Christmas, of course!), and so I'm not going to go all out, and spend a hundred dollars on some crappy gift that they probably won't like very much anyway. I'm all about the sentiment of the day. I just want to make people feel lurrrrrved!
