Thank you for answering this! so it also depends on which school your kids are going.Supermarket school uniform is generally cheap in my experience, you can get a 5 pack of polo shirts for around £6 for example. My kids primary aren’t bothered about logos so we can get pretty much everything from asda/Sainsbury’s. A single polo shirt with the school logo on would cost around £10.
It’s the logo stuff that costs more and if your school requires it then that’s where it starts to get expensive as you can’t get those from the supermarket. It’s usually secondary schools that are guilty of this but it’s not unheard of at primary level too.
I feel bad for the children that are going to a school that want them to have the uniform with a logo and where the parents can’t afford it. School shouldn’t be a thing that costs a lot of money.
