Amazon has a bulk sized 84-ct. box of Crest Supreme Professional Whitestrips for $59.99! That’s only a little more than the price of a smaller box in stores. If you use these regularly, this is the lowest per-strip price that you’re going to see!
To compare, the standard boxes that sell for $29.99-$49.99 in stores have between 20-28 strips. This has 3 times that many! Also, these are professional quality and, according to the description, work better than retail whitestrips.
