I left a honest feedback about a memory foam topper....not negative, just not outstanding. Something along the lines of "If I had paid full retail I'd not be happy." I received a telephone call from the seller's agent offering me a 20% discount because I was not happy. I said no thanks....he said no, really. I said okay. He then asked if I would remove the 'not quite outstanding' feedback. I did so because I was without a qualm because it really is a fine item. I'm still glad I didn't pay $500 for it though!
