That is true, even if it is a small gift, if one puts some thought into it, it can be very meaningful.
I'll do what I do every year...take her to the store and together we'll read all of the Valentine's Day cards.
Seriously, I'll take her to her favorite restaurant for Tofu Teriyaki. We're married 23 years, so we've done most of the gift things. And I work in ladies sleepwear, so I've brought home samples of PJ's and sexy stuff over the years.
She still likes to be surprised, even it's something small. And like you say, it takes a little bit of planning...so don't wait until the 14th and then freak.
