Be aware of Acai Berry "free sample". Your credit card will be charged dearly for products you have not ordered and will continue to do so unless you are able to cancel orders. My advice: cancel your credit card and try to get these guys to get you pay back!!! There are couple of numbers that I have been able to get a hold of. In Canada 416 900 1137. US 361 808 8234.
It's wise not to order any free samples online from anyone. Most of these companies are scammers.
