Too bad Woot ran out of the refurbished Kindles mentioned in this thread (maybe they'll get more):

You could have bought a refurb Kindle 5th gen for $19 from Woot, sent it to Amazon for their posted trade-in value of $20 plus the additional $20 coupon, and come out +/- $20 ahead. Probably not worth the effort though, since Amazon puts the Kindle's on sale pretty frequently I think.
