Wow, good try. San Leandro, California police stopped a man after reports he tried to sell an HDTV at a Wal-Mart parking lot. However! It turned out to be a plastic-wrapped glass oven door with Sony and Best Buy stickers.
The man is suspected of trying to charge $100 for what appeared to be a 37-inch flat screen television. He had even stuffed electronic cables and a manual in the back.
San Leandro police Lt. Pete Ballew called it a variation on the old "rocks in a box" scam, in which a box is presented as containing new, expensive electronics for sale but is actually full of rocks.
Most of us would spot the scam a mile away, but it does make you wonder if anyone would fall for it. I certainly know a couple of people (including my Dad) who might. [The Oakland Tribune via Gear Diary via Slashgear]
