expired Free Delivery (No Min Spend) @ Hell Pizza
seems to not have a minimum spend (so technically they will deliver a order for 1 drink that totals $3 including delivery) which is better than their usual free delivery conditions.
officially the offer is only available from the stores below but it seems to work for others.
Available from: Balmoral. Epsom, Remuera, Grey Lynn, Symonds St, Quay St, Victoria St, Mt Albert
