This seems to be an amazing price and seems to be the cheapest full priced game on the Nintendo Wii as of yet, so if anyone is looking for a new game for a major film license for their kids, then you can't go wrong here at only £17.99 including free delivery.
Make sure to also go through Quidco to receive £0.72p cashback, making this title only £17.27 all inclusive (quidco is 4% rather than the 2% stated on the site) and the next lowest price seems to be £31.99, which shows how great this deal is.
I've just noticed that Nintendo Wii games Barnyard and Spongebob Squarepants are also at the same price as Cars (17.99 or £17.27 with Quidco) and are comfortably cheaper than anywhere else and i've just checked, they're all instock right now.
Hope everyone likes this and takes advantage for their kids. :)
