Any Cumulus coupons that you’ve received personally are usually stored online and on the app. These include the Cumulus coupons that you received by post, Famigros coupons sent by e-mail and any bonus coupons issued to you at checkout when you spend more than CHF 100. Now and again, there are also coupons that are only available digitally. Blue Cumulus vouchers, which you also receive with your Cumulus post, can be redeemed digitally too. Digital Cumulus vouchers can only be redeemed via the app.
