I signed up for the free trial of Bright White. I cancelled within the company free trial time limit. I even called my credit card company to tell them I did not approve any further charges from Bright White. I was charged $87 anyway within a couple of weeks. The trick they used was another company name (Nova not Bright White) in Japan, so my credit card company put the charge through. So beware. If you really want to do a free trial, you must cancel the credit card after the charge and get a new number to beat them at their own game. Thankfully my credit card reimbursed me the amount, but we are all paying for this activity in the long run. read full review »
