Well, I hadn't ever seen this before, not really that important, but still quite interesting:
They also sell SD cards:
Well, yeah, around Christmas this year the Mario Kart XL version went down as low as $150 [still regretting not buying one, probably will never be that low again now that it is selling quite well]
$170 for a 3ds? Might have to buy one for christmas.
but still quite a good deal if one wants to buy one at a random time. Especially because it comes with one year warranty.
