Thanks to KindleBoards member hsuthard for alerting us last week to this great Kindle deal: you can get 40% off the Kindle WiFi eReader if you're an Amazon Rewards Visa cardholder.

This special goes on through August 15th. Just use your rewards card to pay and use the promo code KINDLE40.

And there's more: the discount applies to Kindle accessories as well, and shipping is free! You can use the discount code to get up to $100 off your total order.

Check out this KB thread to join in the discussion of our members who are taking advantage of this deal. And, of course, the fact that it's such a deep discount is adding to the speculation that Amazon is clearing out inventory, in anticipation of an upcoming release of new Kindle e-readers.
