Those pre-paid credit cards for when you're going on your hols

[teapot2015]

I've probably left it a bit late to get one of these - travelling next week to France.
Does anyone know where I can get one straight away? With a PIN?
We live in London.
We'd like to use the card to make purchases and withdraw cash ... without all the additional bank handling costs.
And, it would be great to get one where I can transfer more money onto the card as we go along, online or via an APP

Thanks very much

Some of these charge too. Check mse site for the best option.

Thanks Annie, someone at the bank told me that you can actually get them from Post Office, and they would only charge 2 Euros for withdrawals, which isn't bad, I think
