Groupon offers the 2nd-generation refurbished Kindle Fire HD 7" 16GB WiFi Android Tablet, model no. B00FKA9PM4, for $46.99 with free shipping. That's $13 under our March refurb mention and the lowest total price we've seen. (It's also a current low for a refurb by $46.) It features a 1.5GHz dual-core processor, 1280x800 touchscreen LCD, 1GB RAM, 16GB internal memory, and Android 4.4 OS (KitKat). Deal ends June 12.

A 90-day warranty applies, but it's unclear who backs it.
