I once bought a lamp at KMart. When I plugged it in it sparked and blew the circuit breaker. I put it back in the box and taped it shut with some green decorative tape, which was all I had, and took it back and got a refund. The next week I was in there, and there was the box with the lamp, with MY GREEN TAPE holding it shut, on the shelf for sale. I took it to customer service and raised Cain. Guess what? It was back on the shelf the next week.
