(the way we solved expensive international zine shipping was the simplest possible thing: just use letter mail! put a zine in an envelope with a stamp. It took a while to work out the logistics though.) 

 @e06c1f25 It doesn't say what size they are in print. I would want to know that. Also, go to the dark side, and use A print sizes: https://www.adobe.com/uk/creativecloud/design/discover/a5-format.html 

 @0609534c they're 8.5" x 5.5”. I'm pretty unlikely to change the paper size at this point :)
