Questions about Product rows and toasts
Where do the products come from?
From your own Shopify catalog. Castor pulls your products and keeps them up to date, so prices, photos, and stock match your store.
What if a product is sold out or deleted?
Deleted, draft, and unpublished products are left out. An active product still shows even when Shopify reports zero or unknown stock.
Can I pick the products myself?
Yes. Pin specific products in Design Studio, or let a row fill itself from bought together, similar, bestsellers, new, or a collection.
