If you're lucky to have friends who have invited you to join the Estrid club, you can get a free travel case when purchasing the Starter Kit with a subscription. Before you place your order, there are some things to keep in mind:

• Only 2 friends can get a free travel case with the Starter Kit using the same referral link, so make sure your friend hasn't invited too many friends or it won't work.
• You cannot combine the referral link with other discount codes.
• When you order, don’t use the same wi-fi/network as the person who sent you this link, as it may cause issues.
• Now that you’re all informed, you can click on your referral link, and choose "Get Started", and the referral code will automatically be registered in the checkout. If not, you can just copy and paste it as a voucher code.
