I'm not planning to do a digital version. With zines I really like the fun of physical books. Sending them as stamped letter mail, and people getting them in the mail, feels like I'm being truer to the spirit of zines than a pdf or ebook.
I've done my best to keep the price down, and sending them as stamped letter mail is part of it. One to you in Brazil as stamped letter mail is currently just under $5 for the stamps.
