[quote name='Archgarth']Not true, I worked for Costco for 9 years and here's the skinny: Only one coupon needs to be scanned to take off all of the coupon discounts. Each coupon has the same general barcode, and there is no differentiation between coupons. That said, each warehouse has a different coupon policy, and this can vary from region to region, or even within the same city. Annoyingly, this is up to the warehouse manager's discretion. Some warehouses require you to just bring the book with you and the cashier will scan one of their coupons at the register. Some require you to pull out one coupon to hand to the cashier. Some require you to hand over all the coupon items you are getting to the cashier. And some require nothing at all, and the cashier scans their coupon for every transaction.
Check your local warehouse, but a good rule of thumb is to either bring your book with you or pick up a copy at membership.[/QUOTE]
Just as a note, the Wii deal is NOT a coupon. It is just listed in the coupon book so you do not need to bring it to get the deal.
But, in general for coupons, all you'd need to do is bring in one of the barcodes and it is good for all the coupons in the book.
Personally, I'm hoping that there are still copies of Okami sitting around.
