+1, I would worry about overwhitening or doing something else weird at one of those mall places. And then you won't have time to fix it.
I had an event for which I wanted my teeth to look whiter a few weeks ago and used Crest white strips every morning for the 3 days prior and my teeth looked good. I would not normally use them every day like that (it will cause tooth sensitivity) but it was worth it for that event. Now I'm trying to use them weekly so my teeth look whiter more generally.
