As a Click Energy user, they provided a code to get 6 x 28 day Amaysim plan (unlimited 1.5GB) for free. Through the personalised link I found I could also generate multiple code for mates. So I found a way to de-personalise the link for all my Ozbargain mates. Click on the link here, scroll down the page and click on 'generate code'
After the renewals are used up you will start to be billed the $24.90 each renewal. From the T&Cs:
• place a new order for an amaysim UNLIMITED 1.5GB mobile plan (Eligible Plan) through the amaysim website;
• enter the applicable redemption code from Click Energy in the promotion field when signing up for an Eligible Plan; and
• pay with a credit card, debit card or PayPal (postpaid only) when prompted.
EDIT: As of 11:10 PM AEST Amaysim site is reported down for maintenance. We had a good run!
