Gift Box reads your store’s inventory in real time and shows gift availability based on that data.
Behavior with out‑of‑stock products
If a product selected as a gift goes out of stock while the offer is active, Gift Box will not display it on your store.
Exception: If the product has Shopify’s “Continue selling when out of stock” enabled, the gift can still be shown and selected.
