Back from the fleamarket in town. I spent €15. This is what I got:
€7 - Metroid prime 3 Corruption (wii) + Animal Crossing Wild World (DS)
€3 - Original gameboy with very little scratches + Speedy Gonzales (GB)
€1 - Midway arcade treasures (PS2)
€2 - Kingdom hearts (PS2)
Also some non gaming stuff:
€1 Scart switch box
€1 Usb fan for keeping me cool while coding

Yeah I guess there is a bit of luck involved, but it's like this every flea market I go to, so perhaps I am just good at making deals/spotting games I dunno.
