I just got an email about this and I think its pretty cool. Recycling + getting rid of lame makeup + discounts- I'm in!

I doubt that printing off this coupon will work- you'll probably have to sign up as a Beauty Insider and get the email, but most people are probably already members so I thought I'd post.
