While the hot buy for everyone seems to be the 3DS XL deals, which have been increasingly hard to get, don't forget that the normal 3DS is still a great device especially for the younger kids that don't necessarily have bigger hands to hold the XL.
Groupon has the 3DS in cosmo black, refurbished, and includes Paper Mario Sticker Star. Based on the description (manufacturer refurbished, 1-year warranty) these are highly likely to be Nintendo-refurbished items. Free shipping, and while the ad says all applicable taxes will be charged, my Groupon order for 2 went through without applying sales tax (I'm in CA too). Maybe it will be applied later, but we'll see.
Don't forget 4.6% FatCash too (or 6% ebates)
