Not sure whether or not this is a decent deal but the best I was able to find in terms of free games - one of which to suit me, the other for our son! - realise this may be subjective as there are similar deals at Argos for £159 and Toys R Us.
With two games, red and brown version of the console retail on the site at £159, although with the following code: TDC-CCB2 - it reduces the price down to £149 and with a further 3% quidco for Tesco Direct didn't seem too bad a deal so gone for it for our son's birthday.
Features as follows:
Much bigger screens: This is what gives the new DSi its name. Nintendo say that the screens on the DSi XL are a whopping 93% bigger than those on the original DSi, making this the handheld console with the widest viewing area of them all - even bigger than Sony's PSP!
Pre-Loaded with FUN!: The DSi introduced downloads and an SD Card slot, but the DSi XL takes the fun even further with loads of stuff already installed on the machine, ready to enjoy right out of the box! That includes Dr Kawashima's: Little Bit of Brain Training: Arts Edition and Dictionary 6 in 1 with Camera Function and the Nintendo DSi Browser, which lets you surf the web anywhere you can find a Wi-Fi hotspot!
XL Stylus: the screens aren't the only thing that have got bigger. The new-look stylus for the DSi XL is bigger and feels more like a pen, making for a more natural and comfortable gaming experience on touch screen classics like Professor Layton, Nintendogs and Brain Training!
Refined Colours: The DSi XL comes in a deep Wine Red or classy Dark Brown, with a glossy finish on top and a mat finish underneath - making this the classiest-looking portable console currently available equally at home whether you're pulling it out of a handbag, sports bag, zip top or suit jacket!
And of course, the DSi XL also features all of the great new innovations that debuted on last year's Nintendo DSi - like music playing, photo-editing and gaming downloads from the Nintendo Online Store!
