The UK Nintendo store has a New Nintendo 3DS Build Your Own Bundle deal available right now.
For £159.99, you're able to choose a New Nintendo 3DS in your choice of colour - black or white - one of nine sets of cover plates, and get a free Mario Console Holder.
It's not on show, but Dealspwn reckons this bundle also comes with a charger. That's something you don't get with the regular £149.99 New Nintendo 3DS.
If that is the case then you make a saving of about £25 compared with buying the contents of this bundle individually.
