Hey, here's a little tip on how to collect more Cumulus points when shopping:
For example, you buy a lawnmower at Coop Bau&Hobby and pay with your Cumulus Mastercard (from GE Money Bank)! That gives you 1 point for every CHF 2 spent.
The young gentleman at the Coop checkout did react a little confused when I thanked him for the Cumulus points. Of course, you can also do this at apple.com or in the Bally store ...
