My friend sent me a referral link but I’m being told I can’t have a code/my code isn’t working.
This is likely because you have shopped with Koh before, or your discount code has expired. The refer-a-friend discount codes are only available to first time customers, so if you’ve shopped with us before, it will not work. If you are a new customer, the code will be activated with a minimum spend of $50. Alternatively your code may have expired if you did not use it within 48 hours of it being activated. If this is the case, revisit our site through your friend’s unique URL and you will be issued with a new discount code to use within 48 hours.
