You can certainly try - when I got to the registers, the girl was puzzled as to why the duiscount didn't apply and was going to manually override it, but then contacted another operator who also told her to manually override it. Then her supervisor walked by, checked the item on the system to see if it was full priced, then checked the catalogue to see if it was advertised. After confirming it was in the catalogue, she told the regi op that it "couldn't be used inconjunction with any other offer" as stipulated on the coupon.
