Products available online but not supp****

Once again we had an order delivered with products not supp**** yet these products are still available online on the day of delivery. Also many of these products were the reason for our order so it was even more dissappointing.

Please can you have a system in place to rather NOT deliver the order at all if ANY of the products are not available for delivery especially if you are unable to keep the website up to date with the products actually available (I mean how can you NOT have potatoes available?).
