To explain the terms and conditions of this promotion so everyone is clear.
The code can only be used in Pizza Hut Delivery outlets (not restaurants where you can dine in).
This is for Collection only and not delivery (you have to go to the PH Delivery outlet and collect your order yourself) you can of course get someone else like a friend or family member to do it for you.
Also when you order online you put the voucher code in when you checkout and it should deduct the cost of the 2nd pizza.
