then the restrictions:
--directly below the title in small print: excluding Migros-Bio and mixed milk drinks
--above the barcode in small print: excluding M-Budget articles, excluding multipacks and special packs...

My question: Does Heidi mountain milk now also fall under this Migros-Bio label...? which is not necessarily the same as Bud-Bio... ??

What about the cream? --- Is it also milk - just in a somewhat concentrated form - somehow the opposite of semi-skimmed milk, which probably falls under the term in the subject line.

I'm not necessarily a fan of broad terms like total milk range, only to restrict it with a negative site in the small print... I would prefer a positive list (what belongs to it) - something like what@ap82once suggested:

Wouldn't it be a solution if a "Next" button appeared in the M app for these vouchers, and then the images of the products appeared there? It should be technically possible, as the system needs to know what the discount applies to.
Or that after activating the coupon, these items would be marked in the app (e.g. a small cumulus symbol) in the product list or in the shopping list.
