I think there should be an Amazon good deals thread in everything else with the book link (it would get buried and forgotten in B/S/T).
If someone sees a good deal they can share it with the rest of us. We'd have to use your link and do a search for the item, but copying and pasting an item's name is the least we could do for this site.
I'd start one, but I have a feeling by the replies I get that no one over 13 reads my posts.

Once we're at Amazon can we search and click on anything and BOYAC will still gets it's cut?
The first post in that thread could explain the details and how to avoid any Amazon trickery that might void the commission.
