So what about dropshipping and using the merchant's datafeeds to list their products?
Is that kind of a give away in your source code? that you don't own the product line.
In dropshipping, you would be using your own merchant account, your own shopping cart, for all purposes you would be the merchant. The suppliers may have datafeeds but more likely a catalog that you build your own datafeed from. You set the prices, you take the payments, you are the merchant except you do no shipping, maintain no inventory.
You would want to do a lot of research before you set up your business, but that is entirely different from being an affiliate for a merchant. You can do a search here on dropshipping and you may get some information, but ABW
is not a hotbed of dropshipping info. Good luck.
