Where's the best place to buy these DS titles?

Where can I find the best prices for

Phoenix Wright: Ace Attorney
Trauma Center: Under the Knife
Lost in Blue
Trace Memory

Any info would be much appreciated!

Trace Memory is being sold for $19.99 at some KB Toys. Don't know about the others.

You can also get Lost in Blue, Trace Memory, and Trauma Center at Best Buy for $20 after the $10 off $30 coupon. The only place I've seen Phoenix Wright is EB, new or used.

EB's used price for Phoenix Wright is $19.99, or $17.99 after Edge discount. That's a decent price for a fairly hard to find game, assuming it's complete.

My BB never carried Lost in Blue, but Trace Memory and Trauma Center can be had for $20 at BB after the coupon. I have only been able to find Pheonix Wright at EB/GS
