If it is no followed, I don't think you will have a problem and even if it is indexed, I don't think you will have a problem.

If you can add some information about the links (product reviews, why someone should buy something from a particular merchants) to products, merchants or whatever you link to then you've got yourself some unique content and might even pull in some search traffic from those pages ad have a better chance of generating sales.
