Amazon Warehouse Deals via Amazon offers the used Amazon Fire 8GB 7" WiFi Tablet with Special Offers in Black for $28.89 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.98.) That's $11 under our February mention of a new unit and the lowest total price we've seen in any condition. (It's also $21 under the best price we could find for a new unit today.) It features a 7" 1024x600 touchscreen display, 1.3GHz quad-core processor, 8GB internal memory, front- and rear-facing cameras, 802.11n wireless, Bluetooth, and Fire 5 OS.
