Trade in @ gamestop

How much do you think I could get for these 2 games?

1. Call of duty 4 modern warfare ds

2. Mushroom Men rise of the fungi ds

I'm not really sure, but probably not much.

Sell them to a friend or on Craigslist/eBay/Amazon, I guess...

What would be a fun game to by with like $25

I like shooters horror games and action/adventure games
