Once you've created your LALALAB order, simply click "use my credits" on the summary page. All credits earned through our reward or referral programs are valid up to 2 months. You'll receive an email and a notification when these are about to expire. (Though you'll need to have our push notifications enabled). Just so you know, your reward and referral pot can't be used towards shipping charges.
All credits are exclusive to a specific LALALAB account and can't be used by another (unless you purchase a gift card with your credits). If you want to use your credits on your order but can't find them, please contact us so we can help!
