If you like to give your special someone lingerie as a gift for Valentine's Day (this is one of the few times where a present for you is really a present for him), Charlotte Russe's intimates sale has great prices.
Panties start at $2, two piece sets are $10, bras are $5 and up, and camis can be had for as little as $5. The sale ends Sunday, Jan 31.
I have not bought lingerie at Charlotte Russe before but am guessing you'd be better off buying a showy piece that you don't expect to wear often instead of something sensible that you want to last.
