My husband actually pointed out this commercial to me. The Amazon Kindle has dropped in price to $139. The Kindle is actually sold out at this price but you can reserve it now and they are shipping September 17th. This has Wi Fi but the 3G Wi-Fi Kindle is priced at $189.
You can head over here and scroll down to see a comparison of the various features for each Kindle.
My husband just ordered this on Monday and the estimated ship date was Sept 17. But, good news, he received an email Wednesday saying to expect it to be delivered Aug. 30th!
