I printed off the one from guswal above and went directly to Kohls. The cashier said this coupon with this upc bar code has already been redeemed in Brook Park.

It kind of took me off guard and I said, "how could it have been redeemed when I just printed it off 20 minutes ago?" She then took it an entered it manually.

Looking into this more, I think these coupons are emailed to those signing up for email alerts from Kohls and each one has a dedicated upc.
