Have you heard of the Electric Tiki statuettes, specifically the Buffy ones?
If not look here Electrik Tiki for photos. They have released a few(Buffy, Willow) and are planning on doing more, but it seems like the Spike design will get cancelled(btw, it's probably not the same design as on the page I just showed you, I read it's been changed a lot).
To save Spike, show that you care.
Btw, please link to this petition on whedonesque (we're not allowed to link to our own stuff).
