How to get an Orange nano sim?

I recently bought an iPhone 5 having upgraded from an iPhone 4 but I need a nano sim. So I went to my local phone shop hoping it to get cut but they couldn't as I had already cut my full size sim into a microsim. I'm just wondering whether orange replace the sim and at what charge

OK
Did you use scissors or a craft knife?
Yes they do
Charge is FREE OF, I assume you're not talking electrical charge
Do not order it take days, run skip jump. Tra la lah la lah, or however you intend to get there your NEW nano sim awaits.
