Ok GAF, stopped at 3 best buys in the South Bay (Los Angeles area).
Image is El Segundo (upper middle class, upper class area). They are 4 deep, 8 long and 3 high. On top, they are 3 deep, and 6 long. That's 96 + 18 = 114 Xbox Ones. They had a sign with a display box at the front of the store that said "We have Xbox One."
Next stop was Hawthorne, which is a lower middle to mid middle class area. They had a big kiosk inside the door with xbox one accessories. No sign, nor did they have stock out. However, looking online shows they have stock. They likely didn't have stock out for two reasons. The first is that they have little upper shelf space in this store. The second is that BB doesn't seem to want to wrap the boxes with the anti theft devices probably due to their liquidity or size.
Third stop was Torrance, a middle to upper middle class area. They had no sign or kiosk up front. They had two xbox ones in a locked aisle end near the video game section, which is all that would fit. They have little shelf space too, so I'm assuming they have stock in the back like the Hawthorne store.
All 20 or so stores near the 90245 area code have stock last I checked.
