Just did a look see with a code that was emailed to me from the Sox and there isn't much available. I even tried looking at an average game in June, but they wanted $70 for a lower box seat (not in "Platnum" area).
It's more convenient and CHEAPER to go on secondary sites. That is my plan for the opener. Congrats to you that were able to find good seats on the pre-sale!
Next game: TBD
