Thanks! Managed to find a black controller at a Walmart right down the road from me, along with PowerA Play and Charge Kit for $9.

Got the last Sony MDR-XB650BT for $19 a couple of days ago. It was marked for $45, but scanned for cheaper.
Also, found a Sandisk 250GB Extreme Portable SSD for $13 hidden behind the 1TB versions. Not a bad haul.
Been a pretty slow month since money's been really tight. I was able to pick this up for $20 a few days ago.
Popped it into my wife's 360 and works great!
Also got Metroid: Other M from GameStop for $3.59.
