Blizzard White and Bella at Home were suggested by blog All Things Thrifty. Samples of product would cost about a dollar plus shipping. I bought. They didn't deliver for weeks, but in the meantime charged my credit card for two full tooth whitening kits. They will not refund. On the phone they were smarmy, laughing, trying to confuse, and ulitimately not going to refund the more than $200 they stole from me. Both companies I believe are either one in the same or related, as they behaved in the exact same way.
