I know of several top marketers doing this right now.
They advertise a product (not their own) and once a customer buys it, they'll purchase the product and get it sent directly to the customer - obviously keeping the profit they made by selling at a higher cost than the original Ebay seller.
How do they do this? If you buy through Ebay, they only allow you to ship to a few addresses don't they? How do they manage to ship to thousands of different addresses?
I know wholesale is a much better route to take, but how are they doing this??
