Bests & Worsts Reviews from Amazon

When I upgraded my Kindle to this newest model, I got an offer to trade in my most recent model for up to $50. My older model was still in great shape and works perfectly, so I didn't hesitate. Today, I got a note that said I would be paid only $5, but that I could get a 25% discount on a new Kindle! I just spent $250 on a new Kindle, and you want to pour salt into my wound?
