Hey @joelbrock nice one for starting this, but perhaps we could make this a slightly broader thread about Tech for Food Co-ops? That way we can discuss CORE POS and other stuff too 
@chris could you maybe move/ copy the relevant posts from Worker Coop Weekend is 11-13 May - #22 by jdaviescoates and Hello from the Tech Support Cooperative - #11 by danholden threads here?
@joelbrock also, check out these recent #CoopsRetail slides from VME’s Steve Gill (.pdf), shared on this Facebook thread`by Richard Bickle - likely of interest
