GoPro really, really wants to sell you a Hero5. It has even launched a trade-up program to make the prospect of giving up a working older model more appealing. Starting today, April 11th, you can get a Hero5 Black for $100 less than retail or a Hero5 Session for $50 cheaper than usual if you send in your old GoPro Hero devices. You'll likely get a lot more than a $100 if you sell your old model on eBay, but this could be a quick option if you were planning to get the company's latest action camera anyway. Simply go to the program's official page, select the camera you want and follow the instructions on how to send in your old Hero. Just take note that this offer is only available for a limited time.
