Valentine's Day US style - cards sold in boxed sets of 32!

I've just noticed an aisle in the supermarket selling boxes of 32 valentines cards. This seems a bit strange. I wonder if it is a Nevada gambling thing to make sure you have all the bases covered!?

I think the box of 34 American Chopper foil covered cards are the most perplexing. For him from her? For her from him?
