Bonjour, Pourquoi le pack batterie est-il moins chère au détail qu'en option dans le kit principal ? Cordialement Guillaume


Vous avez raison, je viens de modifier le prix de l'option: c'est bien 47.5€

Merci d'avoir repéré l'erreur !

Vous pouvez rafraîchir la page, normalement le bon prix s'affiche.
