After watching extreme couponing, I have began reasarching the world of couponing. My favorite resource is Money Saving Mom. You subscribe and daily receive a newsletter detailing the best deals.Often specific savings are shown for a store and have clickable coupons allowing you to replicate the deal, sometimes for free or mere pennies. I wasn't able to take a screenshot but below is an example of what it looks like.

On my shopping experience I choose to go to target for some household items. Target.com has printable coupons updated frequently. If you are lucky AND smart you will find manufacturer coupons for the same items that you can use with the target coupon. I also compare prices and quantities. Targets brand up and up has similar products to the name brands, often with the same ingredients, for significantly less.
I got all of these products on my shopping trip:

up and up cleaning wipes $3.99-$0.50 coupon=$3.49 

scrubbing bubbles on sale for $2.50

up and up brand swiffer wet jet refill pads 16 for $6.19
