Ebay's cool for buying random things. A lot of times it doesn't come out cheaper esp. after adding shipping cost. But for rare items its cool. I got a pair of awesome custom cowboy boots really cheap, I love them and would wear them everyday but they're blue and don't match a lot.
Hands down Crest, especially with the new Whitening Expressions. Cinnamon Rush is my fav. I thought of the concept b4 it even came out, I wanted a toothpaste which tasted like Big Red and about a yr later we had one!!!Honestly, though I think people tend to choose toothpaste brand base on what they grew up with, if mom & dad uses Brand X then that's what brand the child tends to go for.
