I got my dad a wireless controller for his 360.

He got me a fanny pack with 6 zipper-controlled pockets.

Since the controller doesn't work, I figured we are even.

With fresh batteries, used packaging, grimy cracks, and a $5.00 discount, the only thing I can think of is some miscreant swapped their broken, junky controller for a replacement. 

I am not amused.

Caveat emptor.
