We have someone that specifically works at finding new sponsors. Since the staff positions are all voluntary, it is done on his free time. Right now a lot of companies are pulling back on expenses due to the economy.
I think everyone in SW should check out Underwater Outlet. The shipping is a little high, but when you order say, 7 or 8 different things. That gets it down to below what you would pay per item at the lfs IMO.
