If you can be patient about purchases, and then keep an eye out for a discount, that is ideal. You'll guarantee that your really do want the item or service, eliminating impulse purchases. And you may be able to get it for a steal. One of my favorite coupon sources is the Bucky Book. It is a fundraiser for my Alma Mater (UW Madison), and is filled with coupons for stores I regularly visit (hair salon, kids shoe store, favorite restaurants). And when I need something new, like drywall repair, it is the first place I turn. Happily I discovered a coupon for 50% off drywall repair, which we needed when a foot of snow melted over new years and ended up in our finished basement.
So, that is my view on coupons. I like them, but I know that can inspire impulse buys and view them cautiously. And that is why people call me frugal.
