$7 off of Crest Whitestrips
Whitening your teeth is not cheap. I've never had the dentist whiten my chompers, but I have used Crest Whitestrips, and they worked pretty darn well. They were also pretty darn expensive (around $30 or so).
Fortunately, Crest seems to feel bad about this, so they will send you all kinds of coupons if you sign up to receive their promotional email.
I did, and once every month or so, I get an email with a new coupon link. I don't use all of them, but they're pretty handy when I do. Anyway, here's one for $7 off of Crest Whitestrips. Happy whitening!
