Uber-couponer Kathy Spencer isn’t satisfied with just having a low grocery bill. She only considers it a success if she gets everything for almost free, or even make money off the transaction. She does this by looking for loopholes in the system, like “rolling.” This is where say toilet paper is on sale for $1 but buying it generates a $1 store credit coupon. Use that to buy another roll, get another coupon, buy another roll and pretty soon, you’ve got yourself a year’s supply of toilet paper and you’re handing it out to strangers in the parking lot.
