TC Xtra claims it is Garcinia Cambogia, which is supposed to help in weight loss. They get you to only pay shipping and handling for a free bottle of their product. They then use your card info to charge a lot more money without authorization. When called they say you have to cancel within 14 days or be charged. They do not give any kind of contact information in their packaging or invoice. The only way I got a phone number was by disputing this charge with my bank.
