>>211964743 (OP)I most frequently shop at Coop, this country’s second-largest supermarket chain, but only because I shop on foot, it’s the closest supermarket to my house (maybe three minutes’ walk) and I am lazy. I actually prefer Migros (biggest local chain, also found in Italy and Turkey, fractionally cheaper for a few items, doesn’t sell alcohol) for a lot of stuff (they have a better bakery IMO) but it’s a very slightly longer walk.
I also shop at a lot of my local corner stores, which stay open later and are mostly open on Sundays, but they’re not full-sized supermarkets and most of them emphasize whatever ethnic foods the owners prefer. So it’s easy to get Iranian pickles or Turkish cheese or frozen Sri Lankan food, but not a lot of international or local basics. On the plus side, some of them have better-quality fresh fruit and vegetables than the big supermarkets, just not a great variety.
I buy food. Mostly fresh produce, not much processed/prepared stuff. Also household products, although for cleaning supplies I try to cross the border and shop in Germany, where most things cost a lot less.
Today I bought a bunch of different cheeses, some hummus, some crunchy snacks, and some small carrots and cucumbers, among other things. Oh, also a watermelon and some sparkling wine, because I’m having people over tomorrow.
