I have a store at https://shop.stonemans.com.au/
I am using a 3rd party app called Bespoke shipping to calculate the shipping rate due mainly to the fact i can write a script for it as the store has very complex shipping rules. The shipping calculator works great. Its there at the end but I also have the calculator at the cart page which looks like this (Im using brooklyn theme).
We are however getting quite a few abandoned carts so were hoping to get the shipping calculator to display on the product page, how would I go about this?
Since you mentioned you have already done a lot of customization, you just need to move the calculator from cart page to product page. This will be a code modification and not sure if anyone in community will be able to explain it here. Kindly send me or any Shopify expert DM so that they can look at through collaborator access
