I think a lot of stores incorporate a "cheater" mechanism where if you're on the store wifi they use that as the location. You could pick it up via IP or hardware MAC (even if you are on a VPN the local router still knows your MAC from when you passed the ToS accept portal). Doesn't help cell service of course, and cellular data clients are REALLY tricky to geolocate properly. Cell towers are often trunked a considerable distance (apparently?) so your IP can indicate you're quite far from your physical location. Pages really rely on the browser to cue location in that scenario, but of course many of us turn it off, and at that point you get what you get.
