No longer being sold by Amazon, that's why.
Not true, will be back in stock on the 16th.
looking at it, it is out of stock until September 16th for the 25$ through amazon
Go to Buying Choices->new - the top option is 25$ by amazon
you can probably buy it and they will ship it when it comes in stock
I don't understand how this is a good deal. It's a wired controller.
