Guarantee Cellular via eBay offers the refurbished Verizon Ellipsis 7 8GB 7" 4G WiFi Tablet in Black for $39.99 with free shipping. That's $9 under our March mention of a refurb and the lowest price we've seen in any condition. (It's the best deal now by $10 and a great deal on a 4G tablet.) It features a 1.2GHz quad-core processor, 7" 1280x800 LCD display, 1GB RAM, 8GB internal storage with microSD card slot, 3.2-megapixel rear-facing camera, 0.3-megapixel front-facing camera, 802.11n wireless, Bluetooth 3.0, and Android 5.0 OS (Lollipop).

Note: A 60-day warranty applies, but it's unclear who backs it.
