1)  Think outside the grocery store coupons.
2)  Hit the web.  Register for national and local coupons.
3)  Look for businesses that match other businesses coupons.
4)  Check out coupons mailers and coupon books.
5)  Make sure if you purchase items with a mail in rebate, you go directly home and send in all paper work immediately.
6)  Only use rebates and coupons on things that you usually would purchase. Don't be sucked in on items you don't use.
7)  Spend a little time with  your mail.  There are many postcard mailers that save you money.
8)  Invest in a coupon file so they are organized and at your finger tips when you need them.
