I just picked up Pokemon X from Kmart, had to get a manager to come manually take off 25% because the barcode and number were not working. Wish I still had my employee discount but still happy to get it for that price.
I worked at kmart for a few months and basically 90% is for items that show up on the hand scanner as .01 for the price,, which means it's a discontinued item. At the registers they show up as errors or something from what I saw when buying stuff I found on the floor while scanning. I'm not sure...
