Googling for Coupons

The store site is a good start. There are also sites that contain coupons for multiple stores. DealCoupon and DealCatcher are two of the better ones - these are sites that specifically research and publish coupons/coupon codes, vs. sites that automatically just compile search hits for 'coupon'.

Another source is eBay for 1) newspaper/ magazine coupons - people will clip out bunches of these and sell them in quantity (just make sure you'll actually use them before they expire for them to be a real deal) and 2) exclusive coupons that are distributed to a limited audience, like a store's points-club members - these usually have a significant $ or % cost savings.

I bought a coupon sent to the points-club members of a major office supply store chain. I wanted to purchase a desk that was already 25% off and the store was promoting free shipping for orders over $50. For $4, I was able to purchase coupon which gave me an additional $50 off my furniture purchase of $300 or more.
