In Pathfinder Society, players aren't generally allowed to provide permanent help to other players. However, there is a note in the Guide to PFS Organized Play which says players may share gold for some spellcasting services:
You are also permitted to spend your character's gold to help a party member purchase spellcasting services such as raise dead or remove disease.
This makes sense, because players may be unable to adventure for the gold they need to, say, raise themselves from the dead. But the phrase "spellcasting services such as.." makes me think there might be some limits to this option.
Which spells are available for this type of cost pooling?
