Nothing worse than clipping a great coupon and then letting it expire. If you create an effective organization system for your coupons, you will be much more likely to use them before they're outdated and you'll breeze through checkout without fumbling through a wad of paper.
Some online deals are too easy to find and too hard to pass up. My new fondness for coupons started when I was visiting my folks in Florida. Before entering the Gap Outlet somewhere along the Gulf coast, I found an Internet coupon on the sidewalk: 50 percent off any purchase!
