For example, Clump Crusher mascara for $3 when you "clip" the coupon that page (or $2.70 if you do subscribe and save, which you can cancel later). Most of the products with coupons are mascara or foundation - here's the full list. I kind of want to try the Outlast 3-in-1 foundation, since I've heard it's good. Thoughts? Only one coupon per account, I believe.
There's also a $3 Cetaphil coupon here.
