Yes, just enter the barcode no. as indicated at the bottom of your Cumulus voucher on your way to checkout in the “Vouchers & Gifts” section. You can enter as many Cumulus vouchers as you like. The amount will directly be taken off your order (and a possible remainder credited to your customer account). You can also enter your Cumulus vouchers any time in the “My credit” section of your customer account, or simply scan them with our app.
Every Cumulus voucher can only be used once. As soon as a Cumulus voucher has been entered and confirmed online at Migros Online, it is considered redeemed and cannot be reused elsewhere or cancelled. The Cumulus vouchers expire one year after the date of credit.
