BuySpry via eBay offers the refurbished Unlocked Apple iPhone 8 64GB GSM Smartphone in several colors (Space Gray pictured) for $362.99 with free shipping. That's $7 under our mention from three days ago and the lowest price we could find for a refurb now by $56. (It's also $236 below the lowest price we could find for a new one.) Note: A 60-day BuySpry warranty applies.
With these companies, it might be easier than you think to negotiate your monthly bill down.
