I was the OP on this thread that seems to have digressed a bit. But anyway, I thought I would followup on the results. The manager of the Dover (Tampa), FL store called me as a result of the post. She attempted to obtain the showerhead from another store but was unsuccessful. She agreed to take my shipping information and have the item sent to me when it became available. As it turned out, we were in the Tampa area today and went by the store to pay for it in person. In the interim, they got a supply in and I was able to get one at the sale price with my raincheck and coupon.
I appreciate the efforts of the Tampa manager. My only comment is that the waste of her time and mine could have been avoided if the CW call center would accept coupons when an order is placed. The coupons are uniquely numbered so they shouldn't be able to be used more than once. Anyway, problem is now solved.
