For those who want to just start out selling on ebay, the gosmile is a hot item. Don't buy it from the corp site because they want your minumum to be close to $4,000. But there is a site who has wholesale prices just the same as the gosmile corp site and you can turn around and sell them on ebay. The best place to get them is at www.dewylook.com I use it now and it keeps my teeth nice and white. My son uses it too. I'll have to get his photo up here soon. His look great! It's an ampoule you squeeze on and leave alone for 20 minutes. Saw it on The View and Halle Berry is now using it too. Hope this helps some to make some extra money.
