My husband isn't here to ask at the moment (he's taken the children out for a day so that I can study).
At a guess, this is what he would say if he was here:
1st class stamp: "expensive, because you're always complaining about it"
2 pints of milk: he'd know the price of milk exactly, becasue he's in charge of milk- our milkman bill is linked to his bank account
loaf of bread: not sure, but he knows that we always buy 2 Kingsmill loaves from Iceland, because it's cheaper (I think it's 2 loaves for £1.70)
Six free range eggs: he definitely knows which ones we buy (£1.50 for 6 free-range organic from the veggie shop)
We don't consume chicken and I buy coffee every six months for visitors, so neither of us have any idea.
My husband has a terrible memory for numbers and names, (although last night, he did excitedly tell me that a particular supermarket had an offer on his favourite cheese, and that we should stock up there when we run out
), but when I do the shopping, it would never occur to him to accuse me of over-spending. He trusts me. I wouldn't be in a relationship with someone who thought I was incompetent or conniving.
Although maybe he should divorce me, because I used to go through his receipts and explain to him how much money he would save if, instead of doing the whole lot of shopping at shop A (thus saving an hour of his life), he had bought items 39, 12 and 23 at shop B, items 3,6 and 19 at shop C, and items 8 through 11 at the 99p shop.
He just listened patiently, and took some of the advice on board, and argued that the convenience outweighed the potential savings on the others.
