My local CVS has tons of makeup on clearance. Most of it is 75% and some is 50%, so combine with coupons, you should be able to pick up some cheap cosmetics.
I score the following Rimmel makeup:
Rimmel Mousse Blush (reg. $6.99) on clearance for $1.75
Rimmel Trio Eyeshadow (reg. $5.99) on clearance for $1.49
Used (2) $1/1 Rimmel Product, exp. 2-28-10 (RP 12/13/09)
Paid $1.24 for both after clearance prices and coupons
So check your CVS and let us know what you score!
