There are two ways to get a coupon for a free hot drink:
1) When you register, and add a bank card for the first time, 24U will give you a coupon automatically.
2) Send an invitation to your friend via sms, Email, telegram or other social network (24U gives you the choice to use the most convenient app). 24U will send a message with the link to App Store or Google Play. After downloading the app, on the first page of registration your friend should write down or paste your Promocode. You will get your free hot drink after your friend will make the first paid order. And your friend will get his|her coupon after he|she registered to the app and added at least one credit card to the system.
