I mean, everyone likes free stuff. But that would be really, really expensive for Udemy to do.
There are over 42,000 instructors on Udemy. Let's estimate that it would cost around $15 to print, package, and ship a shirt... given how many global instructors there are and the costs of international shipping, that's probably a low estimate. Let's see... $630,000. I'd prefer they spend that money advertising our courses!
However... opening a swag store where we can purchase T-shirts at a reasonable price... that would be cool 😉
Also Udemy Live attendees historically have received a "swag bag" if you can attend. One year an amazing handcrafted wooden Udemy lapel pin was in there. Still one of my favorite objects.
