This has been covered recently and is something I've used for months now as well, original whirlpool source. Just thought it's definitely worth highlighting as this is tonight's order:
1x Trad Pizza - $5.95
1x Extra Value - $5.95 (might use a Trad and change toppings!)
2x Free Mousse (Thanks TA!)
-$3 (using script)
= $8.90 Pickup
So, Chrome users:
1) Install Tampermonkey
2) Install script linked to in deal
3) Go to www.dominos.com.au, and click through to online ordering
4) Where you normally enter a code, look to the right for the drop down menu, click something and see if it works or not
(Side-note: Many coupons listed but aren't available to you)
Coupon codes aren't displayed, so no way of sharing them, you have to use the script to get the deal!
Just ordered a traditional pizza for $3.95! Going to pick it up on the way to gym… thanks OP!
