I am sure something like this has been requested or suggested in the past, but maybe this time slightly differently. TrainerRoad kit and casual wear only available for order by validated subscribers?
Similar to the Rapha Cycling Club where you must login to confirm your membership to RCC to be able to order member gear. Subscribers (members) advertising TrainerRoad locally across the globe while members pay for the gear themselves just because they are proud subscribers/members wanting to evangelize the benefits of the platform.
I’m not suggesting an Ambassador program of potential freebies, rather a subscriber/member perk that in the end helps TrainerRoad grow without freebies with at least the integrity of only being able to purchase the gear if you are a subscriber/member of TrainerRoad.
