Pretty nifty website that compiles all ticket providers into one listing. It's a good way to snag discounted tickets from season-ticket holders too.
Also, I am considering heading out to the August 12th game against the New York Mets. It's a Wednesday afternoon matinee starting at 12:40 PM. If anyone is interested in joining me there is a package of six tickets for $30 each (regular cost is $60) in section 208 row 8. Click here for a view from the seats as well as other available seats for that game. I wouldn't mind paying less if the majority vote is to sit somewhere else.
