Prepayment for a produce share is a common trait of CSAs, but
they diffr in how they are initiated and structured, and in how food
distribution is handled. Currently, there are three common ways
CSAs are initiated and structured. Shareholder CSAs are formed by
a core group of members who make administrative decisions, and
collectively hire a farmer. Subscription CSAs, in contrast, are initiated
by the farmer who maintains ownership of the operation, makes
decisions, and hires other staf as needed
