So many SDers are looking for Amazon Warehouse Deals (AWD). I haven't found any dedicated thread for that. So, I am making new one.
Please see Last Page for updated links.
Instructions to view category by percent off
Copy Pasted from post # 2689 - Thanks c0bra99
Go to amazon [amazon.com]
Choose a department
In left hand filters, under "Seller", click See more...
Click the "A" in the phonebook style navigation at top or bottom, Choose Amazon Warehouse Deals. (the default view is just "top sellers" and warehouse is not always in the top sellers list for categories)
If you are lucky (depends on the category you chose) you will see a filter option of "Discount" in the left hand filters list. For some reason, not every category has this filter.
