If you like mature cheddar the one in a black packet is amazing, the halloumi is good value too.
we go mostly for the meat in the summer, you can buy a whole piece of belly pork or ribs which I butcher at home to make strips or into ribs much cheaper, I then freeze on a tray and bag up. The salmon is good if you can get it.
you can get big roasting joints way bigger than the supermarket and a better price. If you select one you like the butcher will happily cut into smaller joints for you if you don’t want the hassle at home.
the cookies are amazing but you get a lot so only buy when the family are coming, the muffins can be frozen though so are worth while.
someone else mention the mango chutney, the big one in a blue tub.
you must try the gourmet sauce I think it’s with the soya sauce etc, you use it as a marinade or instead of soya sauce it’s got a high salt content so be careful but its amazing.
the big pizza is good and freeze well.
I don’t really check out the frozen food much but my son says I should next time they seemed to have upped their game
soft drinks - appletizer is way cheaper, other stuff it’s always worth checking prices etc sometimes it’s worth getting sometimes not.
tinfoil and cling film
DH says the razors are good value, some toiletries are more expensive so be careful.
