I purchased a Harman XXV about three weeks ago. At the time, the dealer was running a 10% off offer. It was really just a discount along with the Harman $100 off coupon that equaled a 10% total discount. They told me not to print the coupon since my preferred install date wasn't until five weeks later. My specific coupon code will have expired by that time, and since I paid for installation, they couldn't invoice the unit until it was installed. As many of you know, Harman now offers a $300 coupon that replaced the $100 coupon. I called my dealer, expecting them to say, they would refund me the $200 difference after the install. Instead, they told me I couldn't use the new coupon and get additional savings. I told them, the $100 coupon no longer exists, so there is no coupon for me to present in order to get the $100 savings. They said, "I will call you back in ten minutes." Eight hours later, and I have heard nothing. Am I wrong here? It seems like the dealer shouldn't care, since Harman reimburses them for additional savings I get with the coupon. Any opinions are appreciated.
