Dial up a bargain

If you have an iPhone or an iPod Touch, try CouponSherpa, a free application. When you launch it, you’ll see a list of stores offering coupons (mostly chain retailers, including OfficeMax, Kmart, Yankee Candle, and Dick’s Sporting Goods.) Select a store to see and download a coupon. To redeem it, show the cashier the image on your screen. The cashier will either scan the barcode or type it in manually. (Note: if you don’t have a compatible cell phone, many of the coupons can be printed; go to CouponSherpa.com.)
