We go every 4/6 weeks. DH is self employed, hence we qualify, not sure what proof he had to provide. Costs about £26 pa.
Worst problem is storage as sometimes quantity is quite large, so our airing cupboard is full of loo rolls and the tops of our cupboards are stuffed with kitchen roll and boxes of Kleenex tissues.
Their Kirkland own brand is really good quality.
We buy:
Loo roll (Andrex)
Kitchen roll (Kirkland brand is really good)
Kitchen foil (Kirkland again, heavy duty and lasts ages)
Kleenex tissues
Tinned tomatoes
Coconut milk
Pasta
Rice
Ketchup
Coffee pods
Lenor
Persil liquid
Dishwasher tabs
Cillit Bang
Hummus
Cheese - Parmesan and Roquefort, their selection packs are also good
Pancetta chunks
Pine nuts
Walnuts
Panettone (excellent value when available)
Frozen prawns
Pork fillet (amazing value and quality)
The monthly seafood stand is a great treat.
Even after 3 years, I'm still finding new goodies, I probably need to look closer at the meat, but I have limited freezer space.
I would certainly use the charcuterie for large family gatherings.
I think it's good value for store cupboard staples, but you do have to be disciplined.
