It's my pleasure, really. I know it's not much but I do my best to support small projects I enjoyed and your art alone is worth every bit of money and posterity I can muster.
As for the shipping thing I can't access your shop atm but it was something like 20+ euro for a keychain in shipping alone (which was what made me reconsider getting one tbh) so I think the comic would be even pricier shipping-wise, a book usually rounds up to 30 and I'd rather just give you that money directly when I have it. And that's without the fact that tracking number doesn't really help with barely any civilian flights or carriers refusing to deliver parcels here (I'm from Ukraine so... yeah, would rather not risk it). It's okay, I don't mind digital copies as long as I can buy and read them :3
