Tom Church, a 26-year-old bargain hunter from London, has tracked down discount codes for every Domino's Pizza outlet - so everyone can get a huge discount on their pizza treats.

He didn't mean to compile the list initially; he just started sharing the codes on Facebook. People would ask him if he knew the code for their nearest outlet, and he would find and publish it for them. After it proved popular, he decided to spend three months tracking down the codes for all the 800 outlets in the UK.
He has made the codes available on the deal-hunting website he has co-founded, latestdeals.co.uk. The list is updated every day - and he is donating any money he makes to Comic Relief.
If you are dead keen on Dominos, it's a decent shortcut to any available deals. However, if you are after cheap pizza, it's not the only answer.
There are six great ways to get a cheaper pizza.
1. Eat on Tuesdays
Both Dominos and Papa John's do a '2-for-1' deal on Tuesdays. For Dominos you don't even need a code, whereas for Papa John's you need to use the code AAPJTFT.
If you eat at Strada, then you can take advantage of Pizza Mondays to get a pizza for just £5 - no voucher required.
3. Show your student card
There are loads of discounts available for students everywhere from Pizza Hut to Dominos and Pizza Express. The small print on each deal varies - and sometimes will be different across outlets - so it's worth checking before you order
4. Show your NHS, Fire Service or Police ID
Dominos and Papa John's offer a discount for emergency services staff of up to 50%. Ask at your local restaurant for details of the deals.
5. Spend your Tesco Clubcard points
If you have built up a bit of a balance in your Clubcard account, you might be able to spare some for free pizza. There are a handful of pizza restaurants, including Prezzo and Pizza Express, where you can swap £2.50 of Clubcard vouchers for £10 to spend in the restaurant. It means you could easily treat a family of four for £10 of Clubcard vouchers.
6. Supermarket deals
You don't have to cook from scratch to save a fortune on pizza. At any given time, the supermarkets will be offering any number of deals. At the moment for example, Tesco has 8" and 9" Pizza Express pizzas for half price, so you can snap up a 9" American for £2.25 (plus dough balls for £1.50).
