Now that the any pizza any size offer is over I checked back and theres still a meal deals section with the following deals.
LARGE TEXAS BBQ £10.99 DELIVERED.
BUY 2 LARGE PIZZAS AND GET A 3RD FREE. (for example 3 meateors £14.99 each comes to just under £30 so 33% off)
Online Mealdeal -Any Large Pizza (Max 5 toppings) and a chicken or Veggie Combo and a 1.25ltr bottle of Coke for £18.99
All pizzas are customizable.
Hope these help someone
