Cubic Ninja should be $35 at Gamestop. Just check your local Gamestop, you might get lucky. Anyways, resellers on ebay are usually selling for as low as 40ish now. Though check your local Gamestop first, if you can.
Legend of Zelda + Powersaves is also another option, should come out to around 36.99~ USD on Amazon.
I'm assuming your in America, due to your info, saying Maryland and the American flag.
There's suppose to be a new primary exploit coming out this Friday.
