Expired items.

I am so disappointed by this store. I bought the 3XSheppers biscuits. I check the expiry date on 1 then cause it was a far date i obviously thought the other ones too only to find out when I got home, the Blueberry ones already expired on the 12-06-2024 , why were they kept at the store while they had already expired? I am so disappointed If you need proof please let me know I have even the slip.
