Switch your mates Switch your mates to Powershop For every mate you refer to Powershop, when they switch, you each score a tidy $75 discount. It's that easy. Here's what to do... Log in and refer your friends (we suggest you give them the heads up first). Wait patiently while they follow the link you sent and fill in the sign-up form. They become a Powershop customer. You both get $75 discount, applied as a $25 discount every month for three months.
