no not yet
To be perfectly honest, it just doesn't make sense for me given the pricing. I will usually miss enough games per year due to work and other stuff that it is cheaper to buy walk up tickets. I think it works out to if you miss only 6 games, you are better off buying singles. Since there is really no other benefit to having season tickets, I can't see myself renewing them anytime soon. If and when the crowds come back (man do I hope that happens), then I would buy them just to guarantee good seats even if it wasn't cost effective.
