The Mets still have a few thousand tickets to sell for opening day since its not a sell out for Thursday . On Stub Hub there are over 500 tickets for sale starting at 59.95 . If you head over to Mets.com you can secure seats as well.
The Mets added the Party deck and those seats start at $100.00 but are only available for single games for the first homestand. They include food and drinks. After the first homestand they need to be bought at a group level.
One of these days we will make it to opening day but wewill wait until the little peanut gets a little older.
