Most times you are right about the coupons, they do not allow them to be used on irons.
I however right after Christmas had a coupon for 50% off any one item even if it was a sale item. Well the irons were 20% off and then I used the 50% off coupon and so I was able to purchase a Rowenta iron that was $125 for $47.99.
Don't give up and always check the fine print as miracles do happen. Point of interest on the Rowneta irons look for the packaging that says made in Germany as they are a much better iron and I have had no problems as opposed to those made in China which I have had problems with i the past and had to return to Rowenta.
Good luck
