HUT5901
Found these coupon codes when I ordered pizzas today.
3 Large Pizzas & 3 Sides for $36.95 (Delivered) or $33.95 (Pick Up) [ HUT5901 ]
4 Large Pizzas & 4 Sides for $45 (Delivered/Pick Up) [ HUT5902 ]
2 Large Pizzas & 2 Sides for $30.95 (Delivered) or $24.80 (Pick Up) [ HUT5903 ]
Decided to share them on Ozbargain because they are slightly better than the coupons pinned at the top.
I didn't find an expiry date for those coupons, and thought they should be ongoing.
These coupons are still on Shopback's Pizza Hut page, but they seem not working now. Hence mark the deal as expired.
