Additional Delivery Purchase When Check Out

[Ratty]

It would be useful once someone has filled in their address details to have a button allowing them to purchase upgraded faster delivery.
This is common on many sites.
Does anyone know a workaround, apart from putting it as a product on every page (which I notice that one express site has done - but its messy and time consumeaing when there are 100+ pages)

If you have several postage options and the purchased items qualify for them, then there is a drop down menu at checkout to select the different services.

Or have I misunderstood the question?

Are you sure this is the case with Express? I have not encountered it anywhere?
