I got the Nintendo DSi Green Bundle + Mario Party (or whatever it's called)(Black Friday special) a while ago, and I want to sell it now. I looked on Amazon, and people were selling brand new for like $300, but I can't seem to find any other source to back up the fact that this is a rare item. Also, mine is used, but in fairly good shape, except for the top part of the box (it's also 100% complete).
Other people are selling them used for less but incomplete.
