Will Royal Mail be allowed to charge what it wants for a first-class stamp? | Mail Online

For a number of years now, the Royal Mail has not put the actual price of a stamp onto it, as they did in the past. This means that they save money on printing costs. But how much do they lose when folk like me buy loads of stamps before a price rise and use them later??  Another wheeze that I use is, when a firm doesn't supply me with a prepaid envelope, then I just post my reply without a stamp!!!!
