If your bundle shows as sold out - or its Add to Cart button appears greyed out or disabled - even though every component product has stock, the cause is almost always Shopify's contextual availability. A key clue is that it usually affects only some customers, such as those shopping from a particular country or market.

This article focuses on Markets, Locations, and Shipping. For the full overview of every sold out state (including inventory tracking and app conflicts), see Bundle displaying sold out.
Shopify decides whether a product can be purchased by each individual visitor, not just whether it exists. It checks the customer's market, whether the product is stocked at a location that can ship to them, and whether a shipping rate reaches them. For the full explanation and how to set this up, see Selling bundles from multiple locations and markets.
A Biscuits bundle inherits its availability from its required component products. If even one required component is unavailable to a given visitor, the whole bundle shows as sold out for that visitor - while still working normally for everyone else.
This is why a bundle can look sold out to a customer in one country but be perfectly purchasable in another.
Sold out for all visitors - this is usually the bundle parent product having 'track inventory' switched on, or the shops main location is not enabled for the bundle. See Bundle displaying sold out.
Sold out only for certain countries or markets - this is contextual availability. Work through the causes below.
Shopify only treats a product as available if it has stock at a location that can ship to the customer's region. If the bundle or its components aren't assigned to such a location, the bundle reads as sold out for those customers.
How to fix:
In the Biscuits Bundles app, open the bundle and check the Locations card. Enable all relevant locations, then save.
In Shopify, open each component product, go to Inventory, and confirm it is stocked at a location that fulfils the affected region.

If a location won't assign to the bundle (this can happen with legacy locations), add an SKU to the bundle product and try again.
New bundles start with every location turned on, and Biscuits turns on any location you add later. See Selling bundles from multiple locations and markets for how the Locations card works.
If a market is active but the component product isn't included in that market's catalog (or isn't published to the relevant sales channel), Shopify treats it as unavailable for customers in that market.
How to fix:
Go to Settings > Markets and confirm the affected market is active.
Check that each component product is included in that market's catalog or price list.
Confirm each component is published to the Online Store and any other relevant sales channels.
For more detail, see Shopify's guides on publishing products with international sales tools and creating catalogs to use with Markets.

Bundles do not have their own shipping profile. Shopify works out the shipping rate from the shipping profiles of the products inside the bundle. If none of those profiles has a valid rate for the customer's destination, the bundle can't be purchased and may display as sold out.
How to fix:
Open Settings > Shipping and delivery in your Shopify admin.
Find which shipping profile each product inside the bundle belongs to. Check the General profile as well.
Confirm those profiles have valid shipping rates covering every market and location where you want the bundle to be available.

Reproduce the issue as a shopper in the affected market, in one of two ways:
Add ?country= plus the two-letter country code to the bundle URL, for example https://yourstore.com/products/your-bundle?country=DE for Germany. This works if you have a Market or country set up for that region.
Or open the theme editor and switch the preview's country/market selector to the affected market, then view the bundle. The Add to Cart state reflects that market.
Always check the component product's availability, not just the bundle parent.
Open the bundle in the theme editor to see the detailed sold out reason. See Bundle Form Errors for what each message means.

Work through the checklist in Selling bundles from multiple locations and markets. It covers the bundle product, the products inside it, publishing, locations and shipping rates.
If you've worked through the above and the bundle still shows as sold out, reach out and we'll help. To speed things up, please include your store URL, the bundle product URL, and the specific country or market where the issue happens.
