Newegg offers the refurbished Hisense Sero 7 Pro 7" 8GB Android Tablet, model no. M470BSA, for $89.99. This $40 mail-in rebate cuts it to $49.99. With free shipping, that's tied with our mention from two weeks ago as the lowest total price we've seen. (It's also a current low by $42.) It features a 7" 1280x800 touchscreen LCD, 1.3GHz Tegra 3 quad-core processor, 1GB RAM, 8GB internal storage, miniHDMI, USB, WiFi, Bluetooth, and Android 4.2 OS (Jelly Bean). Deal ends August 31.

A 30-day warranty applies, but it is unclear who backs it.
