Does Marks & Spencer offer foreign currency exchange?

Excuse me, I was wondering if you could clarify something for me. I'm planning a trip abroad and I'm in need of some foreign currency. I was just at Marks & Spencer and noticed they have a lot of financial services, but I'm not sure if they offer currency exchange services. Do you happen to know if Marks & Spencer provides foreign currency exchange to their customers? It would be greatly appreciated if you could shed some light on this matter.
