Current cheapest day-to-day banking/credit card combination

Question: do you know if the 1% cashback you get with the Cumulus credit card when shopping at Migros is in addition to the 1% you get anyway when using your Cumulus loyalty (not credit) card?

I mean, if you have a Cumulus loyalty card you get 1 point per franc regardless of the means of payment you use. This is equivalent to 1% in Migros blue coupons I can get even if I pay with, say, a Maestro card.

Now, with the Cumulus Mastercard we get 0.33% cashback everywhere and 1% at Migros. So do we get 1 or 2% in total? If it’s only 1% then we should use the cashback Amex card at Migros while scanning our Cumulus loyalty card…
