This group of companies attract people to "free trial" offers. They charge exorbitant amounts after free trial period in fine print and rip off your credit card account.
They give you a ridiculous RMA # that is 14 or 15 digits long and make it very difficult to return the products.
Clearly this is a scam where they charge a ridiculous amount for an online sale and then they have your credit card number.
They may also sell your credit card number.
