Living Rich With Coupons

I've been playing around with cutting coupons and my friend turned me on to this great website:
http://livingrichwithcoupons.com/
If you are interested in saving money on your grocery bill, I suggest you check out this site. She has some fantastic ideas.
The basic concepts are:

1. wait til something goes on sale to use your coupons


2. 'stockpile' enough of frequently used items so that you don't have to buy until it goes on sale again (sale cycles are approx 4-10 weeks)

There are tons of coupons available online that you just have to print out.

I have already gotten a bunch of stuff for 70-90% off original price -- even gotten some things for FREE!
