Hi im wondering does anyone know best site to get crest whitening strips?
Try ebay-there are always people there selling
I always get mine on eBay from a uk seller! Not any in particular just look for the best deal!
Got mine on crestwhitestrips.net or something like that. They were very reasonable too.
I got them on value venture site before aswell - seen v.reliable too!
next questions-what way do they work?thanks
There are new ones out called advanced seal, meant to be better than before. Don't move around as much in your mouth
ive just ordered mine i hope they work
