Unfortunately, you can't use any manufacturer's coupons at Costco. That shouldn't stop you from shopping at the warehouse giant, as they offer their own discount coupons on many items you can't get at other stores. Costco doesn't allow shoppers to use coupons from regular newspaper manufacturers or printed on the Internet. Their membership guidelines indicate that they do not accept promotional coupons from the manufacturer, except those distributed by Costco, nor do they accept coupons from competitors.
Unfortunately, Costco doesn't accept coupons from typical manufacturers found on the Internet or in newspapers. Despite not accepting coupons from manufacturers, Costco has its own savings coupons that it offers its members through in-store brochures and coupons that are sent by mail. Costco has a comprehensive coupon policy that allows you to use manufacturer coupons, store coupons, and manufacturer-specific Costco coupons. Some coupon offers are only valid for item combinations (such as buying Tide detergent and Bounce dryer sheets).
To get the best discounts, you'll want to see what the current coupon offers are so you can take advantage of them. The only conditions are that the coupon must be from a brand sold by Costco and that the coupon must be up to date. Costco shoppers should know what items are on sale, which can help them accumulate savings when using store coupons and cashback apps. Although Costco originally mailed its coupon books, its current process (starting in 2011) is electronic.
However, it's worth mentioning that since you can't use coupons from manufacturers and stack them up like you would at other stores like Target, not everything at Costco may be the best deal. Meanwhile, manufacturers often simply charge the cost of a coupon program to the original price of their product. Therefore, to solve this problem, Costco avoids these manufacturer coupon programs to ensure that buyers get the lowest possible price. Coupon offers (also known as members-only discounts) are automatically added to your account if you have a Costco membership.
You can only use one coupon per item, as each product must have its own UPC code or SKU number for the cashier's computer system to scan it. However, once you have the Costco Shop card in your hands, you can shop at any Costco branch and even use the store coupons that you'll have to cut out and present at checkout, since you're not a member. In conclusion, Costco doesn't accept coupons from manufacturers, but it does offer members discounts that provide more savings than manufacturers can offer.
