I got this email and thought I would pass it along and share the coupon code for anyone looking to get tickets:
As a subscriber to Vineline, the Cubs would like to offer you an exclusive discount to the Monday, June 11th 7:05 game vs the Houston Astros.
As a result of the rain out earlier this season, the Cubs have announced a makeup game for this date. You are being offered this unique opportunity to purchase tickets at a 50% discount. We hope that you take advantage of this special opportunity to see the Cubs on a June night at Wrigley Field.
This is a limited time offer and subject to ticket availability. To purchase tickets, please click on the link below and when prompted for the coupon code, enter "vineline".
I don't know if there are tickets left or not, but it sure is worth a shot!
