Some Costco make you rip off coupon by coupon. My Costco just scanned a bar code on the side of the cashier and they don't even need my coupons.
All the items have the same UPC code.
Yes like 1 week..I believe
Yeah my Costco makes me rip out the coupons even though I also noticed they all have the same UPC code....which means its more like a members card where as long as you scan it, you'll get all the discounts. Kind of makes sense since you always see the cashier just scan one coupon and toss the rest. Honestly though with this kind of system I don't really get why they even bother with the clip coupons though...
