The Shame Factor

I know that rich people become richer by practising simple economies. But I gotta confess that the shame factor prevents me from using coupons as often as I should. Today, I went to Target to buy a gift card for a friend. And since I had some time to kill, I decided to use some of my free trial coupons. A 16 oz. bottle of creamer, a package of Airborne, and a bar of Cacao Reserve dark chocolate. When I went through the checkout line, the clerk scanned all of my items. But when she tried to scan the coupons, the computer kept prompting her to manually key in the price of each item. Well, that meant that she had to back up to a prior menu and then scan in the coupon and then the price. Repeat that process 3 times, and you have one very frustrated clerk and a mortified customer who avoided the eye of everyone in line behind her. Let's just say that it'll be a while before I try that again. Maybe the trick is to limit myself to one coupon per visit?
