2 Game Trade Deal

Hey guys, never done one of these trade deals before.

Wolverine has the 2 $10 minimum game trade deal to get the game for $49.

If I go TODAY with two games to trade can I pre-order the game and lock in the $49, or do I need to trade the games when the game releases?

Basically is it $10 minimum value right now, or when the game releases?

Cheers.
