this is my first year taking the plunge. have to say, it's an INCREDIBLE value for the seats and games that i picked: 5 games, 2 Diamond Club tickets and parking pass for each game. Orioles, Reds, Braves, Mets (4 tix for this game) and Phillies were the games chosen. had i bought these games and parking passes retail w/o the group it would've been about $2,900...but with the group it came to about $1,800.
the great thing is these seats are all-inclusive and i chose the games based on what the season ticket holder had available. they had every game except Cubs games when i signed up. the bad thing? they sold their tickets cash only, you had to pay upfront via PayPal or cashiers check and there was a 5 game minimum...no credit cards, no payment plans. still, i thought it was a good deal.
because i joined the group i can buy additional regular season tickets and if they're available...PLAYOFF games.
there are different season ticket groups throughout the stadium. there ticket prices seem to be at or slightly above what the plan holder paid per game, but well below the retail price for the same seat. tickets are straight from the plan holder, not a broker. there are still some games available in some groups, but you may have to do some searching for the game of your choice and be mindful if there's a minimum game purchase.
if you didn't know about this before, take a look and see if it might work for you. if not this season, there's always next season.
