Teeth whitening has come a long way in the past few years. Why would you want to over pay for Crest? I was at CVS one day and found a tube of their brand of whitener that you use with a flexible mouth piece. Just a quick 5 minutes morning and night. I put it in while I do my hair. Results in like three days and it works absolutely great....it is only $4.99. You can actually find tubes of the gel at the dollar tree. Tooth whitener consists of hydrogen peroxide and glycerin....there is no reason to pay $30+ for it on a strip. If you are really determined to use Crest...just go to their website and join. They send you coupons and samples periodically.
