Hello, I just signed up for my first order and was hoping to try the Green Curry with the promotion for new email listing members. Unfortunately I got the email with the code for the curry after I had already checked out. I tried to apply it to my next subscription cycle but it kept saying the code was invalid when done through the edit feature.
Hi @meep7687 thanks so much for joining us here on the forum! 
So sorry to hear that you weren’t able to use the promotional discount for Thai Green Curry on your first order!
You can definitely use it on a future order. If you need help applying this to an active subscription order just send our support team an email at support@huel.com and be sure to include the email address your subscription is linked to and the discount code. One of our agents would be happy to sort this out for you!
