Sounds just like a SCAM !

Yeah, I had a couple of guys in a van recently try to sell me a TV and stereo speakers at a convenience store. I said “No thanks” and turned to walk away when they moved closer and started pushing their sales pitch harder.

I pulled out my phone and started taking pics of them, their van, and the merchandise in the back of it (which included the license plate) while still backing away. They quickly hightailed it out of there disappearing faster than a fart in the wind.
