On 8/21/08, I ordered Acai Berry sample and paid $4.87 shipping and handling (on my Visa). I received sample today, and when I looked for info on cancelling further shipments and payments, I found only sites saying this is a scam and people have been unable to cancel. I'm embarrased to admit that I don't have the name of the website on which I requested this sample. All I have is the return address (P.O. Box) on their mailing envelope. Thank you.
