I'm exploring the advantages of setting up an Amazon store powered by AOM. Is it possible, and how trivial is it, to add your own reviews to products/groups of products? I would like to guide my shop's visitors to find the products that would benefit them the best and also trying to avoid duplicate content penalties in SE-s by adding unique content. Anybody doing this already? Please PM me your URL if you have a store doing this. Thanks for any input you can add!
