This telco has slashed $300 off iPhone 15 models

Optus is offering a $300 discount off the price of nearly the entire iPhone 15 range when you sign up for a plan over 24 or 36 months.

If you're not planning on upgrading to an iPhone 16 come September then now might be the perfect opportunity to get last year's model for less. 

The full $300.24 discount works out to be a saving of $8.34 per month on a 36-month repayment plan, or $12.51 on a 24-month repayment plan. If you cancel the plan early you'll forfeit any remaining discount and need to pay out the full cost.
