Amazon (s AMZN) is now offering free, two-day shipping on all Kindles including the Touch and Fire. To take advantage of this offer, customers simply add a Kindle to their cart and select two-day shipping when they check out. Amazon has seen a huge surge in demand for its Kindle devices, and this new offer is a way to keep the momentum going. I am personally a big fan of Kindle Touch, though you can’t beat the price on the lowest-end Kindle. I used that to read on my recent European trip searching for new ideas in the old world.
