Costco Scores One

My wife cut out all of the needed coupons from this month's Costco's mailer and we ventured to the store. At checkout, she handed the cashier a handful of the coupons for the items we bought and she was surprised he only scanned one of the coupons before throwing all of the others into his trash. She was obviously concerned she wasn't going to get all of her discounts, but he assured her that once he scans one of the monthly coupons, all of the relevent discounts for our purchases would be rewarded on the receipt. And yes it was. Error free with little chance of missing one.
