DS is going to a weekend sports event in Sweden. All meals are covered, and I'll give him some snacks to take, but as the debit card on his junior bank account cannot be used abroad, I would like to also give him a small amount of cash - around £25, for spending money at the hotel, venue, gift shop, airport etc.
Problem is, all my usual pick-up places for currency (Sainsbury's, Tesco, Post Office, M&S) either have a higher minimum spend, or else can't seem to get Swedish Krona by Thursday, which is the latest I would need to pick it up.
Before I do a trawl of other currency outlets, does anyone have any helpful advice?
