I know E4 have done this before, but this time it's for ANY pizza ANY size, included is Stuffed Crust and cheezy bites.
Also included orders delivered. Nice considering this doesn't usually include stuffed crust and cheezy bites.
ALSO, there's something on the site that if you have a voucher from a competitor then they'll give you a garlic bread. And everyone has Dominos vouchers normally! I should add that this part of the promotion is only available for collection.
