Is it possible to calculate shipments without having added an address? The shop I'm building is only serving one country, so I could theoretically calculate shipping costs as soon as a product is added to the cart. Going through the code I think I probably need to build my own

Spree::Stock::Estimator

class and then call

order.create_proposed_shipments

during an orders

:cart

state. Is this the way to go or are there any other preferred ways to achieve this?

Yes, I think it’s a good way to go. Maybe you’ll have to use a “fake” address at some point, without associating it with the order.

Thanks. That helps 👍
