Update November 2022: Unfortunately Migros Bern stopped Migros Plus, you can’t singe up anymore an all active subscriptions expired after their last renewal.
Migros has a subscription service which they try to be a bit like Amazon Prime.
It’s called M-Plus and costs CHF 9.90 per month. Currently the service is only available in the cantons of Bern, Solothurn and Aargau.
Main benefits are no minimum order fee for Digitec and Galaxus, no delivery fee for Micasa (even for big furnitures), SportXX, Bike World, Melectornics and Do It + Garden.
You also get 2x Cumulus points anywhere where you can earn Cumulus points, 3 cents of per liter of fuel from Migrol and 10% off your most purchased products from Migros (in store and online). In the online food shop you pay no delivery fee when you order for at least CHF 99 (which is the minimum order amount anyway).
When you sign up you get the first month for free, when you use referral code Remacc you get a second month for free (and I get a month for free as well).
