Guarantee Cellular via eBay offers the refurbished Unlocked Apple iPhone 5 32GB Smartphone for Verizon and GSM carriers in Black for $99.99 with free shipping. That's $30 below our February mention of a refurb and the lowest price we've seen. (Outside of other eBay sellers, it's the best deal for a refurb now by $20.)

Note: A 60-day warranty is included, although it's unclear who backs it.
