Groupon offers the refurbished Unlocked Apple iPhone 5 16GB GSM Smartphone in Black or White for $84.99 with free shipping. (BuySpry via eBay charges the same.) That's $5 under last week's mention and the lowest price we've seen for an unlocked iPhone 5. (It's the best deal for a refurb today by $5.) Deal ends May 24.

Note: A 30-day warranty applies, although it's unclear who covers it. Also, the item will have minor dings, dents, or smudges and comes with a non-OEM charger.
