Refurb4Less via eBay offers the refurbished Unlocked Asus ZenFone 2 64GB 4G LTE Android Smartphone in Silver for $159.99. Apply coupon code "P20FINDYOURTECH" and pay with PayPal to cut the price to $127.99. With free shipping, that's the lowest price we could find for a refurb by $52. (For further comparison, it's also $7 under last month's mention of a new one with 32GB storage.) This GSM phone features a 5.5" 1920x1080 IPS touchscreen, Intel Atom Z3580 2.3GHz quad-core processor, 4GB RAM, 64GB internal storage, 13-megapixel rear-facing and 5-megapixel front-facing cameras, 1080p video capture, 802.11ac WiFi, Bluetooth 4.0, microSD card slot, and Android 5.0 (Lollipop). Deal ends May 18.

Note: A 90-day warranty applies, but it's unclear who backs it. Also, the coupon can be used once per PayPal account within a single transaction.
