Valentine's Day is not about buying love, its about show love. One way you show love is buying gifts. Just about every holiday is commercialized, especially Christmas. Should we hate every holiday?

Although I see what Bingo and Gaffer are getting at, and I definitely think there's some truth to the observation that Valentine's Day is over-commercialized, nonetheless I'm inclined to agree with Warb on this one. Valentine's Day is as meaningful as you want to make it. Personally, I choose to see it as a special occasion on which to buy my wife flowers and candy, not an artificial obligation to do so. Of course, I don't consider it a hassle to buy gifts for my wife in the first place...
