Hello,
There are a few questions I would like to ask to get a better idea of your situation.
1. Do you only run an e-shop? So you only sell your products online, no physical store?
2. Do you actually sell the products or your doing affiliate marketing?
In most cases, I wouldn't actually put it on my e-commerce site because having advertisements on your store seems unprofessional. The only place I would actually put ads would be in the blog section.
