Ok, I've looked at the cost of sanex. Fairly sure my homebargains sells it much cheaper but at the moment superdrugs doing it for £1.50 with free home delivery & topcashback will give you a few pence towards it (literally as cashbacks not great at superdrug but every penny etc). You could order 12 and hide them for dispensing as needed.
Could he switch to a double edge razor? Replacement blades are very cheap and he could have a fancy shaving set for Christmas which needed blades.
Men are very resistant to change so I usually do things but don't tell him. If he notices I deny all knowledge, he thinks batchellors marrow fat peas are the best but hasn't noticed the switch to Aldi ones.
I've found a lot of veg freezes really well, since doing this I've cut down on waste & I spend less. Lovefoodhatewaste has lots of storage tips, I would imagine things like apples and pears keep well in a plastic box in the fridge, it comes from abroad ok so it should last a while once it's actually here. Try tinned & frozen fruit, especially berries. Asda had 1kg of pears in juice for 50p last week. Much cheaper and perfect for winter puddings.
I don't know what to suggest wrt to fussy eaters, my childhood didn't involve fussiness because there was one option for meals & tough if you didn't like it. Cod roe sticks out but looking back I realise they didn't have much money. It must be a bit tiring cooking multiple meals though.
You won't be missing out, you'll have more money in the bank for one thing, and why should you help buy the CEO of Tescos next yacht?.
All this talk of bread and butter puddings is doing me no good at all.
