I'm going to show you how you can make a lot of money by undertaking JV' (Joint Ventures) with eBay sellers.
You won't need to have a product just a list of people to email to offer the product to. Or if you do have a product, you can find a good seller to sell it for you.
Why should they buy it? Because it'll be a quality product (you'll have sourced it from eBay) and you'll be offering it at a vastly discounted price that they cannot get anywhere else.
