Walmart doesn't really sell anything I'd buy other than maybe some home supplies (get these other places most of the time) or food. I'm not worried about food (rarely shop there anyways) / home supplies like dish soap for the most part myself, but yes that is true. I also don't use it enough and such myself. ----- Plus they can do that already or have done that already with a regular check out (person). I don't know if the security cams (other cams and such) scan for stuff and/or items you are buying. I know some places do this type of stuff when it comes to regular cameras if not security cameras (working in unison).
