Same here, I'm fairly certain that's a thing [1]. Anecdotally, I've started turning off wifi/Bluetooth in the parking lot before entering a big box store like Walmart, and it seems like I get less ads for stuff in the aisle of the store I walked down. Ironically, this method of tracking is one of the conter-arguments I've heard to the "Facebook is recording my conversations" theory. I don't know enough about it to understand how this attack is different than in-store phone tracking.
