As with SamIAm, I have often lamented the poor choice available to single shoppers. But truth is, if you have a freezer, or a market near you, and/ or you're counting the pennies - you can make it work. Just does take a bit more time and effort. But then again so does looking after a family.
I separate and freeze items on date of purchase. Works equally well with FRESH bread products if eaten within a month. If it's grim when you get it out, throw it out for the birds, I mean you've paid the money anyway. If you're hungry enough you'll eat it, trust me.
Markets sell everything singly. From one egg to one sausage to one courgette. Doesn't have the same eat-by dates as a supermarket, but if you are prepared to shop twice weekly you will be okay. Just takes a little more meal planning.
Of course since I moved in the with 'rents I've benefitted from a far larger freezer, and can buy larger packs of discounted meat (Sunday morning, Sainsbury's - fantastic) that we will use in family meals, or meals for Mum and me.
I do admit I am so excited that I'm buying meat for 3 + 1 leftover I get carried away. Dad moans, "Can't get anything in the bloody freezer!" and I sulk. But it's only really about not having to separate into single portions.
And making a list.
Why don't they sell single gloves?
Because they want you to buy another pair.
I'd send you all our right handed ones (Dads is usual dishwasher and is left handed, so that's the one that wears out) but Mum uses the lone right ones when Grandad or the cats have an accident. Put a sign up somewhere in the neighbourhood. You might find a similarly thrifty lefty
