Hello Faouzi As a Famigros member, you receive a 5x advantage coupon for every birthday of a registered child. This coupon is registered in the Cumulus account approximately one month before the child's birthday and can be activated online in the M-APP or at https://www.migros.ch/de/cumulus/coupons-und-angebote.html. The 5x Famigros advantage coupon is only generated for the child's birthday. Kind regards Sofia
