Hey! Thank you for reaching out to me. I completely agree with you. I couldn't find a way to enable free shipping. Giving it some time, I realized the best solution is to simply create a digital-only product on the website so now you can buy the digital ROM version with free shipping at this link:

Thanks again for letting me know you were having this issue :)
