Once you sync a product to your store, our system automatically checks if the product is in stock every few minutes. If an item of a particular brand, size, and color is no longer in stock, we automatically change the status of your product to “out of stock.” Hence, the variant becomes unavailable in your store.
When the item is back in stock, we automatically change the status back to “in stock” and your variant becomes available in your store again. To learn more about ot-of-stock items, see the FAQ article here.
To see which of your product variants are out of stock, go to My Stores in your Printbest™ dashboard. Click on View Store and then the Out of Stock tab.
