I found this helpful hint for uncovering Amazons hidden discounts
Step 1
Get the Amazon Department Code. this is stated in the url as node=xxxxxx In our case we will be looking for musical instruments so the node will be 11091801
Step 2
Paste this address into a new browser tab
http://www.amazon.com/gp/search/?nod...&pct-off=75-99
"http://www.amazon.com/gp/search/?node=11091801&pct-off=75-99"
Step 3
Chane the discount range. This is indicated by the last 4 numbers in the address string. In the example given the search would be for discounts ranging from 75-99%. Just change the numbers as you want and feel free to experiment. For instance if you want to see only discounts more than 85% you would enter;
pct-off=85-99
Step 5
Use Amazon's tools at the left side of the page to filter and narrow your search.
The good thing about this is that it will uncover discounts that are often hidden and hard to find. I guess you could really turn up some great bargains by running this search on a daily basis. Oh, and to search for things other than musical instruments just substitute the appropriate node for another department.
Happy Bargain Hunting!
