Shipping for different types of items

Site URL: http://www.niagarafilm.co

Does anybody know if there is any plan for shipping by store options? I have 3 different store pages on my site as I run a small scale film lab, I sell cameras/film, and im planning on selling shirts. 

The issue i'm having though it Setting up shipping for each is impossible. The film lab I want the options to pay flat rate for shipping, dispose of the negatives, pay for me to drop them off if they're local or let them pick them up. The cameras I want just a shipping cost, drop off, or pick up option, and for the shirts i'll be using printful and need just a shipping option. 

Why is this so difficult to implement? does anyone know any workarounds? 

Mhm I understand your concern but I'm afraid you can't do this on Squarespace
