Proceed to COS and add items to your shopping cart. Just before completing your purchase, leave. If COS's marketing team is on point, they will reach out asking you to complete your order. Often COS will include a promo code to convince you to finish the purchase.
Coupon extensions like Honey will test codes for you on the fly when checking out at cos.com. These apps aren't always perfect, but when they work they can save you time and money.
There are many reasons a promo code may not work. Some of these include product exclusions, order limits, price thresholds, and other restrictions. Make sure you test all promo codes first before completing a purchase. If your cart is not discounted immediately after entering a promo code, it likely does not work.
Occasionally COS will extend a promotion or reuse a code at a later date. If there are no active codes, try out some older ones -- they just might work!
