We do! Every time a friend signs up with your referral code, they get $20 off their first box, and a $20 credit is applied to your account. To send your code, log into your GreenBlender account, and click on the banner at the top of your account page which reads “Give $20, Get $20.” Put your friend’s name and email address, and hit SEND INVITE. They’ll be sent the code they can use at checkout to get the $20 off. Or, you can copy and paste the code anywhere you’d like - share on Facebook or post to Twitter!
