The great thing about Shopto is there fast delivery method, as the site states that all orders completed before 5:30pm will be dispatched the same day and 99% of the time will arrive the next morning, which has happened for me every time i've ordered.
This is one of the best selling gaming franchises in Nintendo's history and is now available 12 days prior to release and is only available at 3 other stores this early but this is the lowest price.
I previously listed this deal from Softuk which had the deal 23 days prior to release and was successful with all that bought it but now it's available from Shopto for £3 cheaper.
The privalege of owning a game weeks before release is always great (i bought an N64 6 months before everyone else, which was about 10 years ago and paid a hefty premium prices but was well worth it) and has received some decent reviews and will undoubtably be one of the most entertaining multiplayer games on the Wii this year.
Don't forget to go through Quidco to receive 4% cashback, which makes the deal at only £27.83 including delivery.
Hope that helps. :)
