GoPro has a history of allowing its customers to trade their existing cameras in for something off the cost of a new model of this brand. However, this offer has never been available in the European Union's (EU) member-states before. This has now changed: customers in these 28 countries can now "trade-up" their cameras for €100 (about US$112) off a Fusion or Hero7 Black's price.
