Free: Contests & Raffles.
What about putting it in a cooler with some dry ice for a few days while I research around (ie, do what I should have done last week)?
Honestly you need to get it off the skull and cooled. IF you cant get it to them just cut off the skull plate and toss it, plan on buying a cape in the future from whoever you have mount it. Unfortunately there is no room for procrastination when it comes to death and decay. How long will it really take to get it to someone to pull it off?
