An ex-girlfriend once won over me with nothing more than a bag of heart-shaped SweetTarts. I love those things and have ever since childhood.
I've never been much of a recipient or giver of those often blecch chocolate hearts (a lot of them use imitation chocolate with very dubious fillings) and the price of real chocolate has only gone up in the last few years (have you noticed how those old ten-packs of Reese's Cups, Kit Kats and other chocolate bars have been reduced to just six per pack while the price has stayed the same or even risen?) to the consternation of a few people I know.
Flowers and cards are one thing and they're great. Thirty bucks worth of sketchy chocolates that may or may not be industrial waste from China coated in imitation chocolate is another.
