I have signed up as an affiliate for various vendors. I would like to prevent my site visitors from be redirected to the various vendor sites to make purchases. I would like to have a shopping cart system that allows me to sell their products, get my commissions, and not have to warehouse the items. Is there a way to do this?

if you mean products such as clickbank products than no, I don't believe you can do that. I have never seen it done. If you mean selling products from a manufacture or drop shipper than yes, you can.
Not sure if that is the question you were asking or not.

I not really sure I understand you question. But will all affiliates you do not need a shopping cart at all. all you have to do is send the buyer to the sellers site and you will get pay a commission. I have build my hole online business around selling other peoples ebay products and making a commission. I have also started a blog on this topic. Check out my sig for more info. Hopes this helps

Yes, the questions is not clear unfortunately. Are you going to make money for referring customers to other sites/stores? Or are you going to resell products of other companies? These are 2 different business types and thus you need different systems to achieve your goal.
