I don't know if it's illegal to sell coupons but apparently there are some sites which offer coupon clipping services. They clip coupons from magazines, newspapers, etc and sell them to you. They save you the need to buy two or three newspapers so you can get coupons from them, so they say. Have you ever bought clipped coupons? Would you do it if you knew the coupon would save you more money than you'll spend buying it?
