That means your friend already uses the Gourmet Passport app and wants you to enjoy the savings too! Before you buy any Offer Pack, go to the ‘Enter a Code’ page in the app and type the code you have received. Once you use the Referral Code you should ONLY purchase the Max Pack because the benefit of the Referral Code only applies to the Max Pack. Once you purchase the Max Pack both you and your friend will receive a cash back in your Gourmet Passport accounts worth Rs.100. This cash back can be used towards the payment of future Gourmet Passport Offer Packs or other rewards, from time to time. For more details please read our Rules of Use.
