I am living in London and I have a Monzo bank account in pounds.
I would like to send by mailbox some cash money on it and I have already done it with cheques so far but that time it is some french cash. Do you think it is possible? The money will arrive in pounds in my bank account?
I’d defo try to find friends or family who go to Europe and wouldn’t mind some Euros, then you can swap for close to exchange rate, the closeness depending on how little of a bother it will be to them and how much they like you.
Heck, even if you sell to them for a huge discount, at least you don’t have to queue up the post office to get absolutely fleeced by 20% and then see them selling your same Euros to the person behind you in the queue for another 20% margin!
