Hello everyone! Apologies in advance for the rookie question/topic. I found a local DTG printer for my tee shirt company and I'm having issues with shipping calculating at checkout. I've created a general shipping profile with all products under that profile with weights, dimensions and package options. Is the reason it's not calculating is because it's a local printer and not integrated with Shopify through an app, etc. (hence having to customize my Shopify store)? Do I need to customize my store with Canada Post APIs through my business account? Please help this rookie! This is one of the final steps to me getting my business launched!
