Inventory and fulfillment

A customer’s selected store affects which products are available and how an order can be fulfilled. I connected that store selection to availability, pickup, shipping, and split-fulfillment options across the product page and cart.

I replaced inventory values maintained through Shopify Flow with queries to Shopify’s GraphQL Storefront API, and updated the cart to preserve the customer’s fulfillment selection.

Getting the loading order right

I fixed a race condition where availability was checked before the selected store had finished loading. The fix reuses cached store preferences when available, or waits for the store to load before resolving availability.
