Martin Lewis, founder of MoneySavingExpert.com, is recommending that people buy stamps in advance of a price increase scheduled for April 7. The cost of a first-class stamp will rise by 10p, going from £1.70 to £1.80, while the second-class stamp will see a smaller increase of 4p, from 87p to 91p. Lewis emphasizes that buying stamps now can save money for those who frequently send mail, especially considering that stamps without a listed price remain valid after price increases.

In his article, Lewis highlights that this bulk-buying strategy has proven effective over the years as stamp prices have risen significantly. For example, a first-class stamp cost only 60p in 2012, making the current price of £1.70 seem steep in comparison. By purchasing stamps in advance, consumers can avoid the impending price hikes and potentially save a considerable amount, especially those who send many letters regularly.

Lewis's advice reflects a common consumer strategy to mitigate rising costs in everyday essentials. As postal rates increase, it's vital for consumers to stay informed about such changes and consider proactive measures to manage their spending. His message serves as a reminder of how small purchases can add up over time, especially during periods of inflation and price hikes.
