Ideally this would be able to be seen right on the order line as you decide to order a quantity. There are a million ways that you could implement this, but I have attached two mockup drawings of what I *think* might be the simplest with the current database structure.
When viewing a catalog item an icon (heart in my example) would appear if public reviews for that item were available.
Clicking on the icon would bring you to a listing of all the reviews (user + review would be listed)
To add a review you would add the item to a favorites list and enter a public comment.
Make sense? Don't know if others would desire this as well. Chime in if you do.
