I've noticed similar with different magazines. I wanted to subscribe to a popular magazine (can't remember which one it was), and it would've been significantly cheaper to order a digital subscription AND a monthly paper copy i the US, than a mere digital subscription in Europe. How is a digital delivery more expensive than a paper copy? Obviously there's some type of price gouging going on here. Needless to say, I didn't take the subscription as it felt blatantly unfair.
