Frequently Asked Questions
How does it work?
Generate a personal referral link from this page and pass it to a grower you know. When they place their first order through it, a credit is applied to their order and a matching credit is sent to you against your next pack.
Where do I find my referral link?
Enter your name and email above and the link generates on this page. There is no account to log into. We also email it to you after your first order, so it is easy to find again.
Which email should I use?
Use the same email for your referral link as the one you order under. Your credit is matched to that address, so if the two do not match, the reward cannot be applied to your next order.
When is my credit issued?
Your credit is issued once your friend's first order is marked complete. It arrives by email as a personal code to apply at checkout on your next order.
How many people can I introduce?
There is no limit. Each grower who orders through your link earns a separate credit.
Does the credit expire?
Credits do not expire. Once issued, your code stays valid until you use it.
