Two of our reliable sponsors of past shows don't have dealer tables at L.A.con IV, which leaves me short of sponsors for prizes. I can fill out the prize pool with stuff from Emerald City -- we have a lot of books piled up here -- to go with the two Cargo Cult certificates and one Casa de Fruta/Hollister in 2008 package -- but I need eight sets of prizes even though we probably won't give them all away. Any suggestions? Anyone there have contacts to dealers you think might be willing to stump up a gift certificate? I'm reluctant to cold-call people at this point, if only because I'm short of time.
