Where can I get a new .hack Quarantine the cheapest?

[neonglow]

I managed to get the first 3 for less than $20 each, but I'm having a hard time finding a copy of the last game for cheap. Please help me.

can find them used at EB Games for around 21 AC sometimes. 1 and 4 are the most easy to find, 2 is sort of hard and 3 is super hard to find sealed ... They had part 4 Sealed at meijers around xmas for 29
