I sold my 3DS on here a few weeks back and have a few games still to get rid of. Games will include normal first class delivery, if you wish for it to be recorded then there will a further £2 on top of the price.
Pokemon Y - £20
Super Mario Bros 2 - £25
Mario Kart 7 - £25
Super Mario 3D Land - £23
Payment will need to be via Paypal Gift. I'm not too sure on the pricing so offers will be taken into consideration if sensible proof is given as to why the offer is good - these prices were taken from amazon/argos and reduced from there.
UPDATE - Only Mario Kart 7 remains, looking for £23 via Paypal gift.
