I work at the large orange home improvement store. We have two stores within about 30 minutes of each other. We have a chronic problem with shoplifting but with a new slant. Okay, so what they do is lift from one store and return it to the other, get store credit, and then sell the store credit to someone for cash. Unfortunately for a lot of them we have a district shrink guy who tracks the thieves on his interconnected cameras, the connections are of all the stores in the north part of our state. They let the shoplifters bring the merchandise back, give them the gift card, then as soon as the person is out of the store they invalidate the gift card/store credit. The shoplifter doesn't know until they sell the gift card and whoever us stuck with it comes back to the thief. I can only imagine how that goes...
