Deal Frenzy via eBay offers the open-box Samsung Galaxy Tab 4 7" 8GB Tablet in White, model no. SM-T230NZWAXAR, for $137.99 with free shipping. That's $2 below our mention of a new tablet from last month and $10 below the lowest total price we could find for a new one now. It features a 1.2GHz quad-core processor, 8" 1280x800 touchscreen LCD, 8GB internal storage, front- and rear-facing cameras, 802.11n wireless, Bluetooth 4.0, microSD card slot, and Android 4.4 OS (Kit Kat).
A 90-day warranty applies, but it's unclear who backs it.
