Vulcan Challenger II 4 Core 8″ Windows tablet with keyboard – Frys – $57 with promo code/free ship

Don’t expect much for this price. The model appears to be unique to Frys, but similar tablets were sold elsewhere (like Walmart) with less storage and mixed reviews. You need to be on their mailing list to get this deal (if you’re not, sign up here for the next one). The keyboard looks like a keyboard case, not an attached keyboard.
