Your LALALAB credits can be used as a discount on your order total by ticking "Use my credits" on the summary page, just before you proceed to the payment page. Please note that all credits earned through the reward or referral program are valid up to 2 months. You will be notified when they are about to expire, but remember that this notification service is not available if you blocked notifications from the LALALAB app from your device. Additionally, your credit pot will not cover shipping expenses.
