Signed comic books... New tier or paying for shipping? (Patreon)

Hi again! Last poll I promise

Ok, so regarding the signed comic books, we have two viable options: 

either creating a new tier for 5€ (5,91$) 

or makign anyone eligible every month but thay'd have to pay for the shipping + the envelope and the protection.

Shipping can go from 15€ to 25€ (17,74$-29,56$), I'd provide the invoice for the shipping and everything. The envelope with the protection, to make sure the comic book arrives in perfect condition, would be 2,40€ (2,84$)

Let me know!
