Way back when I worked as a service tech atr a Beast Buy (The spelling is intentional). I opedne da box on a HP computer and found a bunch of taped firewood packaged in thebox. I figure the computer was stolen at the warehouse.
Earlier this year I bought a knife at Walmart, I opened the box (it was a name brand I bought.)> Someone switched the knife out for a cheapo piece of junk. I showed it to the sporting goods manager, he got me another and commented that he had seen this before. The loading dock people were stealing them blind he said.
Way back when, Mrs. Swordmaker and I bought a Panasonic 19" TV from JC Penney's for $319. We picked up the sealed box from the loading dock and brought it home. When I opened it, we found about $2500 in small electronic merchandise packed in the box. Penney's electronics department manager was NOT pleased.
