For many years I ran an office from home. Used to keep a good supply of various denominations of stamps, plus a postal scale and would be able to post anything quite correctly and happily. Around twelve years since that office close, but I still have my book with various stamps eg 1p, 2p, 10p, 20p etc. etc.
I know that as from the end of January 2023 I will no longer be able to use these, so added them all up and it came to nearly fifty pounds worth!!!
Downloaded the Royal Mail claim form and am returning these. The few first and second class stamps I have will be used by me before the end of this year. Will not purchase any more of these without the new barcode.
