Someone posted on Scam.com that PayPal restricted their account after joining TwoDollars.biz because it violates their TOS (Pyramid schemes, etc).
I don’t know about the quality of the product they’re selling, but the way they have their sales page worded it reads like a classic chain marketing scheme.
Although the sales page at TwoDollars.biz states that it’s selling people Master Resale rights to the eBooks…a close read shows that what’s really going on is that people are buying Master Resale rights to sell the Master Resale rights to the system which sells Master Resale rights to the book AND exact system which is in fact a chain marketing scheme.
I’d recommend you stay FAR away from something like that.
