I know exactly what you mean both as a limited funds buyer and hopeful writer/artist in Croatia.
I find it difficult to buy a comic without reading it before so this model - 'online reading then irl buying' - would be what I would expect from my own readers (when/if I get those)
I've had little time to indulge in comics recently, but I've got you on watch so I'll be rooting through your work soon enough!
