I was checking out some promotional stuff that Dominos sent me, and the deals were pretty good. But what I also noticed was that each coupon said "See opposite for terms," and in the terms it clearly states "No coupon required."
Therefore, simply call Dominos and before placing your order, quote any of the following:
Buy one pizza, get one free (medium/large)
50% off when you spend £40 or more at regular menu price
Free combo when you buy a large pizza at regular menu price
Free garlic pizza bread & bottle of drink when you spend £15 or more
Any 9.5" pizza + garlic pizza bread & potato wedges for £8.99 (from the menu or create your own with up to 4 toppings)
All these "coupons" expire 01/01/2011. They all say "excludes ice cream".
I personally usually order about £20 worth so I think the second one's the best!
If the driver asks for a coupon just say you left it at work when you ordered!
