My garage has changed my tyre valves (1€ per valve).

Question from visitor, 28/01/2015 :My garage changed my tyre valves, I paid 1€ for each one. Is this normal?
Answer by rezulteo, 28/01/2015 :

Every time you change your tyres, you should replace the valve to prevent air loss. It would be a pity for the tyres to wear out faster just to save on the price of a valve.
