After noticing the no Country for Old Men deal I have found that if you use the web address used in 'Go to Deal' ( http://www.zavvi.com/offers/the-times.list
) then add any of the DVD's you fancy in that list to your basket then they will be discounted accordingly.
Add Bourne Ultimatum to your basket, priced at £12.85. when it goes into your basket it comes to £11.56.
Add Donnie Darko to the basket too and end up getting a bigger discount on both items.
It seems that the more you add then the discount becomes that little bit bigger, meaning you will be getting a DVD cheaper effectively if you add it 3 times instead of once.
Note: You must only use the 'The times List' of items to add to the basket. this is the only way that discounts will be applied.
Hope I have made that clear enough, but its late and no doubt i've forgot to mention something.
The cheapest DVD's you seem to be able to buy are Chopper, Donnie Darko and No Country For Old Men. The more you add then the bigger the discount.
I think once the quantity is above 4 items in the basket then the discounts will stop.
Anyways its worth having a look if your after something that happens to be on that list.
Remember quidco for extra savings.
