ONE MIRRION TWOOPS

i sold it for 40

" i sold it for 40 "

Honestly, more because black ops is coming out and they will make some kind of deal. Maybe $20
 
 
 
but, my gut tells me to tell you that you will get a cookie

30 - 40

About $40 sounds right. 
 
You would probably get something like $20 or less at GameStop, though.

You should tell us if you have the case. Giving details helps a lot.

I'm thinking around 15-20 so long as you have a case and it's not in shit condition. I'm sure since Black Ops is on the way you might get a little more especially if you're trading it towards that. This is assuming you're going to gamestop of course.

$30-40. Maybe a little lower. Retail price for this game is still pretty high so you can get away with selling it near the retail price at a bit of a discount.

Did no one check Gamestop's website? It's $32.99 used. You will get probably $10 give or take a few dollars.

Around $30. Once Black Ops comes out expect that number to drop significantly.

At gamestop? $3. Not a typo.
