This is quite a surprise to me, but Sephora has theNARS Cream Blush in "Enchanted" (from summer 2010) on sale for $10. That's a great price knowing that it is sold elsewhere for $29. I've read reviews that the pigmentation is lacking on medium and darker tone skins, but you can read Temptalia's review and see how it looks on her skin.
What do you think? For $10? I have a feeling that this will be sold out soon though!
