After getting this morning's offer from the Timbers to the Season Ticket holder wait list for an 8 game pack of obstructed view seats at $20 per game, I became increasingly curious as to exactly how badly ticket sales were going.
A quick check of availability for Sunday's opener - just 4 days away - offered me a ticket in the Value Deck - the lowest price range. Total price $35.75 with all the numerous, onerous fees. This one was in 222, behind the visitor's section. I made several checks on different sections, and the only one I've found unavailable is the TA, though other sections which I have not checked may have also been sold already.
A check on the Sounders game in October told me there were no tickets left for that one.
One possible cause for the unsold tickets is the mark up on single games compared to season ticket prices. For example, a single TA ticket for STH's is $18. If you want just one game, that same ticket costs you $45.75. (Or at least the same priced ticket in 209 - $35 - is $45.75 with the fees.) Value Terrace seats work out to the $35.75 I mentioned above, compared to the $5 your neighbor paid for his Value Terrace STH ticket. Granted, these are the prices for the more expensive tier of games. The value terrace for Toronto is $15+fees and the TA is $25+fees.
Interestingly, faced with the prospect of the sell out streak ending, the Timbers do not seem to be making a push to let people know their chance to see a big game has arrived.
