Will the post offices in the UK give a very good exchange rate on cashing travel cheques as opposed to banks?

I have heard that the post office will not charge any fees to cash my dollar travelers cheques over there, but I am now wondering how their exchange rate will compare to the banks, such as Lloyds Bank?



Anyone know?



Thanks for your answers!Will the post offices in the UK give a very good exchange rate on cashing travel cheques as opposed to banks?I don't know about the comparative rates but the PO doesn't charge commission when you buy currency such as euros.
