This coupon promotion applies only if you have an Amazon Chase VISA credit card, or if you are willing to apply for one and qualify before the end of this promotion which is August-15-2012 (barring any complications, they usually give you a decision within minutes and you can begin shopping right away).
This promotion gets you 40% off the current prices of the Kindle e-Ink models (4th generation) that have buttons-only. The models with keyboard or touch-screen or the Kindle DX or the Kindle Fire do not qualify. Only the two models shown above.
You must enter coupon code KINDLE40 in your Amazon shopping cart and pay for your purchase with an Amazon Chase Visa credit card (partial payments work as well if you have a gift card balance - or you can contact the Amazon Chat customer service and ask them to put a temporarily freeze on your gift card balance so you can pay with the credit card).
With the coupon code, the Kindle with Special Offers drops to under $50 with free shipping. This is brand new, not refurbished! The Kindle without Specials Offers drops to under $70. The coupon, as its name suggests, is 40% off the current prices.
The promotion is also good for select Kindle accessories. The accessories are not limited to the two eligible Kindle models. All the Kindle accessories linked through the promotional page are eligible. The biggest deal perhaps is the official Amazon Kindle DX leather cover which you can get for $18 after the coupon ($30 - 40% off).
If you are not sure whether an item is eligible, add to cart, make sure the Amazon Chase VISA card is your payment method, enter the promo code KINDLE40, and see whether the price drops at the top right corner of the Amazon Checkout page.
What is nice with this promotion is that you can use it multiple times for multiple eligible Kindles and eligible accessories. You have a limit of $100 in savings before you can no longer use it. The $100 limit, for example, is enough to buy three Kindle with Special Offers models at a discount (40% of $79 = around $32 discount for one Kindle. Three times $32~ of discounts is just under $100 of total discounts). Check the Terms and Conditions in fineprint at the bottom of the Amazon promotional page for the details.
This promotion ends August-15-2012.
