Whoa! Amazon is selling the refurbished Kindle with Special Offers for $69. And if you claim a free voucher from Amazon Local (available today only), you can get it for $49!
Start by heading to Amazon Local (the city doesn't matter) and clicking Get Voucher. Make sure to complete the process of "placing your order" (an Amazon account and credit card are required), keeping in mind that you won't be charged anything for the voucher.
When that's done, click Your Vouchers (top-right corner of the page). It may take a few minutes to finish processing and actually become available for use. When it's done, you'll see a View Code option. Click it, then copy the code that's provided.
Now head to Amazon and add the refurbished Kindle to your shopping cart. Go to checkout, apply the code, and choose Free Super Saver Shipping.
And that's it! You just scored a Kindle for under 50 bucks. And although it's refurbished, it comes with a full one-year warranty, same as new Kindles.
In case you're not familiar with this particular model, check out CNET's review of the Kindle with Special Offers. My daughter has one, and she loves it. It's amazingly thin and light, and its battery lasts forever.
For this price, it's almost impossible to pass up.
