Sports shops in every village rent skis, boots, helmets and sledges by the day. Booking lessons and rental together can bring a discount.
Supermarkets
Coop and Migros sell Swiss chocolate, biscuits and cheese for far less than souvenir shops, plus snacks for mountain days.
Ask who made a piece and where. Check materials and shipping. Bargain politely only where invited; respect fixed prices in boutiques and artisan shops. Prices are fixed in Switzerland and shops close early on Saturdays and all day on most Sundays outside tourist areas.
