I thought I had Sephora (et al) sorted. I'd only go in when I had a coupon or other offer. Except now the offers and coupons come way, way more often. I picked up some necessities (primer, waterproof eyemakeup remover) with a 10% off coupon, only to get teh 20% off deal, complete with special offers if you came in opening night. Which I did, and walked away with a lot of decent samples (full-size in some cases) and such, but I definitely didn't need all the items I bought, like Too Faced's Glamour To Go.
