Quick question for you more knowledgeable folks out there.
I have a bunch of 1st Class and 2nd Class stamps laying around the home. If I wanted to send a small letter using the '1st Class Signed For' service, which currently costs £2.25, could I use a combination of my 1st and 2nd Class stamps to pay for this?
For example, a 1st Class stamp is valued at 85p and a 2nd Class stamp is valued at 66p. Could I go to the Post Office and attach 2 x 1st Class Stamps (£1.70) and 1 x 2nd Class Stamp (66p), which totals £2.36, and use that to pay for '1st Class Signed For' delivery service?
Sorry if this sounds completely barmy. I think I remember my mother saying in the distant past that you could do this, but I don't know if times have changed now.
Many thanks for any help!
