Hello, after searching multiple forums thought I share an easy solution for multiple pickup locations without an app, or installing code or using multiple location inventory tracking.
Inside Shopify > Products > Scroll to Quantity > Choose Edit Locations and from here you can select the locations that will display on checkout.
You have to do this for every product but still a good workaround. Hope this helps.
We have the same issue! We have a working solution, but it is not ideal.
Here's our situation and what we do for our team at www.shush-fashion.co.uk
We have 11 stores and central warehouse to service our website. Our customers can order online and use "Click and Collect" from any of the stores.
What we did was edit the shipping rates, to include our Click and Collect locations. While it is not 100% the solution, it is a workaround we are currently using until Shopify sort this out. Here's what our Shipping Zones look like.
