So I have to wonder a bit about your communication strategies...
In the past, I have often expressed the wish that you should add an availability query to the products so that you know which product is available in which store. Now there is such a thing (I don't know how long) and it is not announced. At least not officially, sometimes as an announcement in the news or wherever. I only came across it by chance through some answers to inquiries. However... I think the query on produkte.migros.ch is a great thing. At last the disappointment when I can't find a product and the unspeakable running around looking for a particular item has come to an end. Now you just have to link the function to Migipedia, which I hope will happen with the announced update. Until then, I just have one more bookmark in my favorites list.
