Consumer expert Martin Lewis has made an important clarification regarding the deadline to use or swap old stamps, as you may have more time to do so than you might think.
While the Royal Mail told Martin Lewis' website MoneySavingExpert that January 2023 was still the deadline, they added that there would be a six-month "grace period". This would mean stamps are valid until July 31, not January.
Martin himself touched on this in his latest weekly newsletter for the money-saving and consumer site, stating that old stamps can be used and swapped after January.
