Bestbuy still has mostly functional phones. I recently went by my local one to play with a Pixel 4A before buying it there unlocked. When I worked at Radioshack (2010-2013) we had mostly dummy phones except for the companies that were desperate enough to have "dumb" demo phones that felt like a real phone but just played a looped video on the screen.
My guess is that Bestbuy has more money so they can afford the rare demo phone getting stolen somehow. Funnily enough when I worked at Radioshack we often had people steal the fake phones that just played a video loop. Someone even tried to return a fake phone once saying that we sold them a broken device.
