Went to my local thrift shop today. It's pretty big and I've found some amazing stuff there. Today they had a half off sale so I swooped in for this:
(It also helps my office is 5 mins away so I can shoot over during lunch or a break in my schedule)
The lot cost me about $15, everything works:

Green Gameboy Color + 3 games (Super Mario Bros Deluxe, The Grinch, Beauty & the beast) - $5 for the lot
Dungeon Explorer for DS - $4
NFL Blitz N64 - $1
Super Mario bros 2 NES - $1 (this entire cart is covered in sharpie. So i'll either make a new shell, or keep as a backup in case anything happens to
the insides of my good version of this game)
PS2/3 AV cable - $1 (can never have too many of these)
Xbox DVD remote - $1
There was a broken Xbox 360 controller they let me have for free because it was falling apart. I kept the cable extension since I often find controllers missing these
and...
BREATH OF FIRE IV FOR $1 !!!
All in all, good day.
