ProBargainHunter analyzed Amazon's URLs and found ways to easily find hidden clearance and deal items by department. For instance, 75% off cameras:

http://www.amazon.com/gp/search/?node=502394&pct-off=75- You can specify a range for the discount like this: "&pct-off=50-70 . To sort the results by price add "&sort=price" at the end. If you want to list just the Amazon products (these would qualify for free shipping with Amazon Prime membership) then add "&emi=ATVPDKIKX0DER" at the end.
