eCommerce plugin

I was wondering if anyone knows of a eCommerce plugin where I can remove the add to cart button at install a new link that would be different for each product.

Since I will selling products on my site, but I have a Amazon Associates so the payment and everything will go through amazon. I just need to advertise the products and have the link on the products page to send them to amazon.

Any plugin do you think would work here, thanks in advanced.
