Pretty sure they do across international borders. Especially in relation on people trying to dodge taxes.
I don’t like it any more than anyone else, but this kinda relationship with Europe was on the ballot in 2016 and like it or not the side won that means prices go up and we have VAT on secondhand stuff. That’s what ppl voted for, that’s what we have, that’s what we will need to get used to. like you say - we will have to shop secondhand locally
