April 22, 2026 We’ve identified a recent change in Shopify’s system that may cause customized products to be incorrectly marked as “unavailable for delivery” or “out of stock” during checkout.
At this time, the issue appears to be affecting a small number of stores, specifically when custom options are applied to products.
Temporary Fix
We’ve found that enabling the “requires shipping” property for these items resolves the issue.
Add this code to the theme.liquid file after the <head> tag. Here is more info on editing theme code.
<script>
/* make shipping required */
function bcpoFirst() {
bcpo_settings.requires_shipping = true;
}
</script>If you’re not comfortable editing your theme code, feel free to contact us. We’re happy to add this for you. Just submit a request through our contact form, and we’ll take care of it.
Ongoing Investigation
We are actively investigating the root cause of this issue to better understand what changed within Shopify’s system and to implement a more permanent solution.
We’ll continue to share updates as we learn more.
