Unfortunately this data is often inconsistent with the visual representation. For example, webshops often list their product as 'InStock' regardless of the actual stock status. Since products are in stock most of the time, you will not find out about this and thus likely extract wrong data in the future.

This was especially apparent when I tried to get my hands on some weights during the early corona pandemic. All webshops were out of stock, but in about 80% of them the schema markup indicated otherwise
