Friends of Click Energy $100 Bill Credit
I work for one of Click Energy's suppliers, and received this special offer via email.
The offer is only sent to their associated partners, but the link is not unique, so anyone can use it - you just need to submit the promo code CLICKFRIENDS when you sign up.
I'm in Victoria, so I get a $100 off bill credit, paid in two $50 credits. They have all the details in this link https://www.clickenergy.com.au/friends-of-click
