Well over here they don't have as many cameras and shit as you got over there so it works better here. Something I read about though, some people said they pulled it off, try it out if you're feeling brave.
Well, first you gotta find a store with an automated teller machine, maybe a K-Mart or something?
The shitty part is that you gotta look all over the parking lot to find a receipt. Then you go in the store and look for the item on the receipt you found. Take that item and also get like a few candy bars or something like that.
Then you go to the teller machine, scan the item you got and then hit cancel so you don't actually pay for it. Then place the item in the bag, along with its receipt. Pick up the bag and set it on the ground (the plate that the bags sit on is pressure sensitive). Then scan the candy bars or whatever and pay for them so if someone's watching, they see you pay for something.
And then you're all set and you walk out. Never tried this myself, as I can't find any stores with automated teller machines around, but some said it worked for them.
It sucks man, cameras have made impossible to steal big things like a PS2s nowadays... This method sounds pretty reasonable.
Worst case scenario... if it doesn't work, the exit's probably pretty close so you just run the hell outta there.
