See the comments for how to get the best deal using this, but by adding both a traditional and a value (rather then two traditionals) you can save more.
*Conditions apply. Valid on 16/01/17 Only. Purchase any pizza and receive another pizza of equal or lesser value. Not valid with any other coupon or offer. Selected stores only. Valid Online only. Minimum delivery order $20. Excludes half n half, additional toppings & indulgent crust surcharges. See below for full T&Cs.
You can still get some good deals with this though:
VOUCHER: Buy 1 Traditional Pizza get 1 Traditional Pizza Free
REMOVE
1 X SUPREME
$13.99 Classic Crust REMOVE EDIT
1 X BEEF & ONION
$0.00 Classic Crust REMOVE EDIT
TOTAL $13.99
I can use a value pizza to absorb the delivery cost, and then use the traditional to get it free, therefore only paying for the traditional and not the delivery cost.
With the 40% off voucher, 1 Traditional on it's own only costs 40x less:
VOUCHER: 40% Off Pizzas (excluding Value and Extra Value)
REMOVE
1 X SUPREME
$12.59 Classic Crust REMOVE EDIT
TOTAL $12.59
Minimum delivery order $20.
lame
In most cases it's cheaper to use a 40% off code than this deal, the 40% off deal discounts both the pizzas and delivery, this code just takes 50% off the pizza price only and you are limited to buying 2.
Example, using this code for 2 traditional:
