That's no excuse, you just have to think out side the box.
For instance, this Slackcountry Brand New Ride Slackcountry 161cm 2012/13
is $300, it's regularly $750+tax.
You have about 1 month till the season starts, you should be able to sell that deck for $500 as it gets closer to the beginning of the season.
Then sell your other deck for cheap just for added cushion towards your new one.
You should have $250 towards your new deck, without actually spending anything out of your own pocket yet.
