I endorse Alley Dweller’s link.
These internet scams have, broadly speaking, 3 players. One company runs the warehouse. The next company makes the brands - there’s no reason why a seller of acai needs to know anything about acai or how to produce it; they don’t even have to handle to shipping and handling. What they do is sell the product for $20 and pay their ad affiliates $40 per sale. They make up the difference by signing the mark up for multiple recurring payments, each of which requires a phone call to cancel. Or you can just cancel the credit card.
The third group are “affiliates” who do the web advertising. These consist of hundreds (thousands?) of typically one man shops. Highly competitive. Lots of experimentation. So basically we have a stadium full of monkeys banging away at typewriters. As it turns out, the result isn’t Shakespeare, it’s “One weird trick.”
