These are basic products that are sorely lacking in your assortment. I've already asked for durum wheat flour and received the idiotic reply that there is no demand. Homemade egg-free pasta is made with durum wheat flour. It also makes excellent bread. All this for people who have an intolerance to wheat and who generally have no intolerance to durum wheat (nothing to do with gluten, but rather with a protein).
Result: I live 20 km from the Italian border and for the first time I went shopping on the other side of the border. Did I buy only the flours in question? No, of course not, I spent around a hundred euros. When I've finished my products, I'll go back and spend three times as much.
So, in addition to the dozens of new products you introduce every week, think of the basic products too. And to think that until now I bought 95% of everything at Migros, including household appliances, HiFi, PCs, and so on.
