Question on Barcode Switching?
Ok, i’ve seen a lot of articles on how people get away with barcode switching. But my question is, if you were to switch an ipod with like, headphones, wouldn’t the cashier notice the difference in prices? And wouldnt it come up as the headphones as it was being scanned? And how would you trick the cashier into believing its the right thing?

Best answer:

or you can just not try to cheat and risk getting arrested
