A group called tickets-for-charity is offering a new way to get premium seats for Celtics games.
They sell seats at less than or equal to face value, but seek a donation (which appears to be about 20-25% of ticket price).
I picked a game at random (2/5/09 vs New Jersey) and found the prices listed above. After following the prompts for the $600 courtside seats, I noticed a $60 service charge.
You then pick which charity receives your money; Shamrock Foundation, Boys & Girls Club, and many others.
Finding courtside seats is half the battle. I can only assume most ticket agencies sell them for double the face value.
So if you have the cash to burn, use tickets-for-charity to get those dream seats and help out a good cause.
