I have a chest freezer JustDavesWife I have a mix of batch cooking, meats, veg, cheese, butter and the beige stuff in there.
I have a pantry. That's tins, rice, pasta, biscuits, flour, sugar, cake mix, oil, baking stuff, uht milk, coffee, tea and cereal.
In the attic is toilet rolls (Farmfoods do 4 lots of 18 for £10), Christmas presents and Christmas sweets and chocolates.
In the linen cupboard are boxes of toiletries which I buy on offer. Under the stairs is booze.
My actual kitchen cupboards look normal if well stocked.
I'm at a point now where apart from essentials I mostly only shop on offers. It took a while but it probably reduces my shopping bill by 25%.
Food Warehouse is great if you want to do a bigger shop without needing a membership like Costco.
