Do you clip coupons or pay full price for items?

Sometimes I will be in the market and notice people pulling out their coupon purses or some people will be rifling through wads of coupons looking for the one they need.

Do you take the time to clip coupons from your local papers and use them in your...

grocery shopping or do you just wing it and pay the full price?

I usually shop at Safeway or Cala Food, because they have club cards, but I see people come in that buy $50 worth of groceries and pay $0.65 for everything, but i dont have the time and I also dont get the local paper (san francisco Cronicle) as I dont read the paper.

In the past, I have read the articles on the Coupon Clipping Queen and even read her book on how she buys like hundreds of dollars of groceries and pays only a few dollars buy using coupons. One has to have the time and the patience to clip, organize and then read the ads for which stores are having what sales and frankly.. I just don't have that kind of time!! ))
