Kandersteg has two grocery stores. The Coop is the one closest to the train station. It has all sorts of food, wine, beer, and soft drinks for sale. Remember to bring your own bag to take your groceries. Don't worry if you forget -- you can get shopping bags at the store, but you'll have to pay a small fee to buy one.
What to buy: Of course, you can get just about whatever type of groceries you want here. My favorite is to buy the generic "Coop" bottle of water. After you drink the cheap and unremarkable water from the bottles, you can refill them with Kandersteg tap water for your hikes. When a local asked me why I bought bottled water when the tap water was so good, I replied that I couldn't fit the sink in my hiking pack. :)
Despite the fact that Kandersteg is a small town, it has considerable shopping options. If you walk along Bahnhofstrasse, you'll find a number of specialty shops of all sorts. You won't find too many bargains here, but if you're a hard-core shopaholic, you'll find just the knick-knack you need to satisfy your craving.
It's the one with the big pig outside!
You can bring your recyclables to this shop-there are collection pallets outside next to the shop. Kandersteg recycles glass, paper, and plastic.
What to buy: Besides meat, a few other grocery items. And I bought a pair of sheepskin moccasins that I'm wearing right now! (and buying souvenirs from the butcher shop is cheaper-hee hee)
Kandersteg has two butcher shops, both on the main drag. One is more in the center of town, the other was closer to our place. Since we were eating at home most nights, we would visit one butcher or another in the morning for our meats. Their selections varied daily. Pork, chicken and fish are prominent. Very little beef. If you want something special--breaded or stuffed or marinated, you can order it in the morning and the butcher will have it waiting for you that afternoon. But be careful, the shops close at 6 pm.
What to pay: A lot less than eating out
What to buy: If you are lucky enough to be in Switzerland in July the black cherries are unbelievable - very jucy and ripe but your teeth will look weird all day!
There are no shopping malls in Kandersteg, but there are plenty of shops to buy food, chocolate, beverages, and knick-knacks.
