GoPro continues to offer its GoPro Hero5 Black 4K Action Camera for $299.99 or GoPro Hero5 Session 4K Action Camera for $249.99 when you trade in any previous-generation GoPro Hero camera. (The trade-in doesn't have to be in working condition; you'll receive a prepaid shipping label to send in the camera.) Each camera also qualifies for free shipping. After trade-in that's about $100 less than you could expect to pay for the Hero5 Black elsewhere and about $50 less for the Hero5 Session.

Both models are waterproof up to 33 feet without a housing and feature up to 4K video recording at 30fps, WiFi, and Bluetooth. The Hero5 Black also features a 2" color touchscreen LCD, 12-megapixel photo resolution, and voice control. The Hero5 Session features 10-megapixel photo resolution and no LCD. Deal ends May 11.
