Watermelon gum, or why I hate coupons

You just can't win with a coupon. I received a plastic, looks-like-a-credit-card coupon from Staples for $10. (Paper coupons are the size of a dollar bill; the original coupon was a wooden nickle--it's inflation.) First I went to the wrong store--it was store specific and apparently they were only sent to certain zip codes. Then the item I wanted, rechargeable batteries, was $19.99, and the minimum amount was $20. I asked the floor clerk about that, and he said Yes, it would count because of taxes. Nope. The check-out clerk said I had to buy something else. So I grabbed a pack of gum, which turned out to be $1.49 watermelon flavored, sugar free, with pieces so small it will get lost in my ample mouth. (I have all my wisdom teeth.) But I did win, in a way. I left the store with only what I came in to buy. Coupons aren't about reducing prices; they are about bringing you in. Or taking you in. Who, but the government, could stay in business by giving stuff away?
