Hi, I have never seen it at this price, Bertocchi ham off the bone at $8/kg (made from 95% pork). It must be an online-only offer as I tried to buy it instore however it was showing at $18/kg. A bonus is Bertocchi is an Australian company using 97% Australian ingredients. It is cryovaced so will last for a few months in the fridge if not opened which is awesome if you are stockpiling for the coronavirus :)
I just bought some and the expiry on it is July, different stores will have different batch so the expiry date will vary.
Edit: worth noting I used the click and collect in-store pick up option. Also, my local store is showing out of stock, however several store close by still has stock in QLD.
