If you sign up with http://www.audible.com/, within 24 hours, you will receive a promo code for $100 off a Kindle!
This means you can get the Wi-Fi only Kindle (With special offers and wallpapers) for only $14!
If you would prefer to have global 3G access + Wi-Fi, you can get it for $39!
This IS a REAL promotion, but here is the catch.
Audible.com is a membership where you pay $14.95 a month, but you can cancel at anytime.
They will provide you with credits for downloading ebooks for Kindle - which, in my opinion, is a good deal since you will be buying books for your Kindle ANYWAY! :)
So hurry and take advantage of this offer!
