The only issue had to do with an add on feature namely the surge supressor. I had $75 dollars worth of coupons but my neighbor had no coupons. I asked for a 2 for deal as he was here cleaning both of our equipement. I was told by him that he could not do that. I guess I expected at least a phone call to see what could have been done. Bottom line was we ether both did it or neither of us did it. I think maybe CM lost a little money at my house today. It was very nice that I received a phone call that they were going to arrive outside the window.
