www.luminousbrites.com has a "free" trial for their tooth whitening product. However, if you do not call them within 20 days of ORDERING the product, not receiving it, you will be charge $88.97, and I was. When I looked on their website and saw that you can return the unopened product for a FULL refund but MUST have a RMA number that you can only get from [email protected]. They say in the disclaimer that you will get a response with this RMA number in 24 HOURS. That was 5 days ago now and I have no response. Coincidently, I received an unauthorized charge on my bank statement from a company called www.fit-fac.com for $29.95 just days after this...hmmmmm.
