How is joining the CSA different than shopping at your roadside stands?

CSA Members pickup their shares at scheduled weekly pickups separate from the stands.
They have access to exclusive produce items typically unavailable at the stands.
Shares are paid in advance rather than at checkout and customized by following a certain format.
Members receive a discount everytime they shop at the stands.
The objective of the CSA is to provide revenue to the farm in advance to assist with start up and off season expenses. In exchange members may receive financial rewards by paying up front. With Norman’s the earlier you join the more substantial your return.
