I flew with a man who quite possibly enjoys coupons more than my little sister. Never except on her face have I seen such exuberance regarding the art of coupon clipping and tricks of the trade. Evidently the secret is that grocery stores in Texas double and triple coupons under a certain sum (say, 50 cents). Coupon manufacturers are aware of this practice and so distribute 55 and 60 cent savings, rendering them ultimately less valuable than those with a lower face value. At this point in the story, this man is poised to burst with excitement. The trick, as a flight attendant, is to collect the circulars from around the country in regions where stores do not multiply coupon face values- these will be under the threshold and therefore will be multiplied in Texas. Also, he advised me to pay attention to the local ads as stores will typically put coupon items on sale a few days or a week after the coupon appears in the newspaper.
Brigid, my dear sister, you are a mere amateur.
