For your first issue, you’d have to find the file with the product template information, and in the product form, add:
if you have trouble finding the file, send here a screenshot with the files in your theme that have the name 'product' on them.
As for the second thing, I'd advise you to check the shipping settings to see about the local delivery and store pickup, and check with a developer about a delivery date picker linked with your calendar, as I don't believe shopify has support for that right now
Please could you indicate which product template I would insert this information into? It would need to show directly after the variant picker section. I have attached a screenshot.
this screenshot only has the files in the templates folder. You won’t add it there. It’s in the sections or snippets folder, something called ‘main-product.liquid’ or ‘product-template.liquid’, something like that
