My husband was at the McDonald's in Chandler, Az. A guy in a blue van came through and asked for directions to Yuma .He said he needed to catch a flight and could only carry on his luggage. He had a couple Luminar l500 projection, smart, 4K tv's that sold in his best buy store for $5000 and that my husband could have it for $300, that my husband was helping him out cause he needed the cash and that he would write it off, that he was closing down his 2 best buy stores. My husband got home and we plugged the tv in and nothing works. The guy didn't give him a receipt so we can't use the warranty.
