Complaint Review: Suntrup Nissan

I received a cupon from, Suntrup Nissan by mail stating receive a free apple ipad 2 with the purchase of any new Nissan.  The fine print stated Iust provide the cupon prior to all negoations.  Upon arrival, I met with Matt, the sales person whom assisted me.  Shortly after meeting him I stated I have a cupon for the ipad 2 thay I would like to use if I decide to make a purchase.  He took the cupon and placed it in his jacket pocket.  My wife and I test drove several vehicles, and the overall service was above average.  Matt(the origional salesmam), my wife, and I began negoations around 730pm.  When Matt was unable to offer a fair price on the vehicle, the internet manager came to negociate.  About 800 when negoations were comming to a close, I inquired about the ipad 2.  I was told they cannot give me the ipad because they already went to low on their price.  Once the price was completely agreed upon I asked for the sales manager to speak to the main manager and try again to include the ipad.  I explained that Matt had been given the coupon upon arrival and I would really appriciate if he could make this happen.  He came back and said they have come down too much, and cannot give me the ipad.
