With your personal code, you can invite friends to get a bloomon subscription. They get a new vase, and you'll get your next bouquet for free. You can find the code in your account, 'Invite friends' and then 'Share your code'. You can also share this code directly with your friends; they can add the code in the final step of the ordering process. In 'My account' at 'My balance' you can see how many free bouquets you can redeem. You choose the size of the bouquet in your account.
