From what I understand, the My Power Mall company makes money because they sign up as affiliates under those online shops that are listed in your personal mall, so when you buy stuff there, they earn a percentage too from those online shops. And if you sign up under the business mall scheme, then you get both a personal mall (for your own shopping) as well as a business centre where you can refer people and earn a percentage when they make purchases too, so there's a downline to work on.

I've signed up too and I can assure you that it is free to sign up. There's no hidden member costs nor do they ask for things like your credit card number to secretly bill you or anything (unless you are making purchases at the online shops, then you have to give your credit card number).

or e-mail me at woo_whee@yahoo.com if you have more questions.

Hope this helps.
