shopify out of stock product still purchasable

The actual problem

OOS variants stay buyable or linked from ads, creating failed checkouts and wasted ad spend.

Do this

1. Inventory → filter Available = 0; confirm Continue selling when out of stock is off per variant.
2. Crawl collection + ad landing URLs for products with 0 inventory still showing Add to cart.
3. Redirect or unpublish dead SKUs still in Meta/Google ads.
4. Re-test mobile PDP → cart for the top 10 paid-traffic products.
