As one of its daily deals, Woot offers the factory-refurbished Kindle Fire HD 32GB 8.9" WiFi + 4G LTE Android Tablet with Special Offers for $179.99 plus $5 for shipping. That's $14 below our June refurb mention and the best price we've seen for this 4G model. (It's a current low by $114 for refurb.) It runs a heavily-modified version of Google's Android OS and sports a dual-core 1.5GHz processor, 8.9" 1920x1200 HD display, and 32GB of internal storage.

Also available is the factory-refurbished Kindle Fire HD 64GB 8.9" WiFi + 4G LTE Android Tablet with Special Offers for $199.99 plus $5 for shipping. That's $70 below our May refurb mention and the best price we've seen. (It's a current low by $144 for a refurb today.) It features the same specs as above but has 64GB of internal storage. A 1-year Amazon warranty applies to both models. Both deals end September 5.
