I would suggest putting your question in Google search, and read the various articles by people who have done this, monitored their sales, etc. I found one but we cannot post links here. I created stores, which is time consuming and put their links on my blogs, but have since deleted them. You have to add each product you want, one by one. The only thing good is that you can create stores per your niche such as baby gifts, or TV's, etc. I have seen these pages on the free traffic exchanges. I wish I could give you a better answer. I have never seen anybody use an amazon store with their hubs. So, I doubt if it is possible.
