I used the Crest Whitening Strips about 6 months ago before a wedding. My family really noticed the difference and I could tell a difference in my photos. I bought them before the price went down (didn't realize the price dropped) and I thought it was well worth the price!!
I will be buying them again and thanks for the coupon link.
A trick I used was to do the top teeth the first week (or two). The bottom strip has a lot of excess that wouldn't ordinarily be used. I cut the extra on the bottom strip and use that on my top teeth. This way I get an extra week or two on the top teeth for free.
I have a friend who tried using the Crest Strips and while she liked the results, they made her sick so she had to stop using them.
