GoPro via eBay offers its refurbished GoPro HD Hero4 Black Edition 4K Action Camcorder
with free shipping
. That's $20 under our refurb mention from last week (which included a $20 gift card) and the best outright price we've ever seen. (It's also the best deal for a refurb today by $44.) It features 4K video recording, up to 12-megapixel photos, waterproof housing (up to 131 feet), WiFi, and Bluetooth.
A 1-year GoPro warranty applies.
