According to Mashable.com The following are the top 7 Valentine's Day gifts by category:
1) Flowers
2) Candy
3) Greeting Cards (hopefully to go with #1 or #2)
4) An evening out (and NOT to something like MMA)
5) Jewelry
6) Clothing (most likely of the bedroom-ware type, I assume)
7) Gift cards- this is the one I find strange. Doesn't a gift card really say "I didn't have time to give your gift much thought, so you figure it out"?
Unless the gift card is 5 figures...then I guess it's all good.
Happy Valentine's Day!
