Argos have come up trumps for this deal on the latest DS (until the next one) with a sub-£80 offer on this black DSi.
With normal prices of £119 online and €149.99 in Irish retail stores, you can't really go wrong with this one.
Argos don't do delivery to Ireland from the.co.uk site, so it looks like you'll have to collect in person or arrange some alternative method of collection.
