I set up my son in a CESA a few years ago. At the time we were told that there was no minimum monthly investment due to the fact that it was a qualified educational savings account. However, recently we started noticing fees for the quarters there was no activity. We decided that due to the fact that this supposed pollicy had changed, gave an order to sell our shares and close the account. Three weeks after our request to close our account they finally sent a check that was 20% less than what the closing amount was.
