I drove skiing to La Plagne in France, bought snowchains for around 30 euros in the big supermarket next to Gare de Aime train station, just before climbing up the hill to the resort. Don't remember the name, there is Decathlon and the petrol station there, hard to miss. However, managed to drive almost all the way to the chalet without snowchains kept them in the boot in case of major snowfall or something. Europcar offered me to rent snowchains from them for 100+ euros for 14 days which I declined.
