Output unavailable Products

Hi there,

I hope you can help me a bit, because I think this web scrapper is the best so far. I would like to get the products from this web shop and it would be best if it were only the ones that are not available. I've tried many things but just can't get there.

That would be a product example: Professional [Mehrkomponenten] Protein kaufen | Bodybuilding Depot®.

could you help me?
