$133.00 Cashback Was $70.00 Cashback
Also go into draw to win a brand new Tesla Model 3 & get $2,000 credit towards their energy bills.
I don't think you can combine with a referral code, however you possibly may get $50 bill credit.
(First page shown when clicked through from shopback says "$50 welcome credit". Not sure if it'll be applied also though.)
