By contrast, the prices of several products that are bought only occasionally, such as household appliances or package holidays, or the prices of services that are paid by giro transfers, for example telephone subscriptions, have typically increased much less or have even decreased.
Understandably, if you are confronted daily by somewhat higher prices for relatively small purchases and you only benefit occasionally from more substantial price advantages for some expensive products, you may well perceive inflation to be higher than it actually is.
