GoPro wants you to buy a new Hero5 camera and is willing to give you a price break to do it. The catch: You'll have to send them your old one first.

For a limited time, GoPro owners can knock $100 off a Hero5 Black or $50 off a Hero5 Session if you send GoPro any Hero camera. And it can be in any condition -- broken, scratched, dented, whatever -- and you can send it in and get a new camera back.

The camera maker has made it simple enough to do, too. Just go to its site, pick the Black or the Session and place the order. You'll get a label to ship your old one and, once your return is processed, GoPro will charge your credit card and ship you your Hero5.

GoPro has had troubles in the past year as it has struggled with weak sales. At least part of that issue is that its older cameras have been good enough to keep even frequent users satisfied. A price reduction never hurts, though, and the Hero5 cameras do offer considerable improvements over much older models such as better image quality, a waterproof body and voice commands.
