Amazon’s Hidden Discount Search Trick

Who knew that Amazon’s search function has a setting for finding discounted items?!

This article from SlickDeals tells how to use it:

For example, do a search for coffee maker. Then append &pct-off=50-70 to the URL (near the top of the page) to find coffee makers that are discounted from 50 to 70%. The results are not prefect, but they are pretty good. Remarkable!
