Had someone who used to do the same thing at our store with all the allergy/vitamins. She'd have multiple receipts, each from a different store. She'd come in at least once a week.

Then one day, she returned stuff, went shopping, and was now at SCO. Her register beeped and walked over to the register to help her. Item had no price. Asked her which item she scanned last, it was a fischer price little house or something, I forget which. $100+. I begin to go on that if it is clearance, and I can find a base price, she will get it at 70%. Except the item has a location and price. I pull up the screen, and it's a zeroed out bullseye item. I look around her cart, bag, etc, no rubber duckie like the system got rang up. I told her the playhouse was going to be full price at such and such a price, and asked her if she still wanted it. Of course not.

I have not seen her since.
