Will Astros home game ticket prices drop or raise the closer we get to game time?

Wanting to go to the game this upcoming Saturday with my family (5 of us). Been looking at tickpick, seat geek, and Ticketmaster, as they’re cheaper than the tickets available on mlbtickets.com.

Should I just wait til we get closer to Saturday to pull the trigger? Or will the prices not change much from now til then? Or, does it just depend, and hard to tell what will happen. Just wondering if anyone knows what is usually best. Thanks!
