Kogan has launched a cheap iPhone 15 deal in Australia by offering customers $50 off and free shipping if you sign up to be a member on its website. Shoppers can become a Kogan First Member easily by signing up for a 14-day free trial to take advantage of this offer. Members can cancel their membership at any time but if you do want to keep it after the two week period it’s $99 annually or $10.99 monthly and – similar to an Amazon Prime membership – gives you free shipping, discounts and access to giveaways.
