Hey First off, welcome to GC and The Greatest bunch of Folks who are here to help Ya!
The first thing to remember, your cost per person for membership will be lower than most Nationals because of Risk Management Insurance.

No House Insurance for Liability, parlor fees, utilities, etc.
The Second thing to remember, is they complain about cost to belong to a Group of Ladies that they can be with then do they really want to join?
I have been involved with My Organization from when I Founded it in 1965 till Today! Some of my closest Friends are not only Brothers from My Local Chapter, but from Brothers all over the Country! One being on GC who I never met but helped refinance my house!
What is one of the great things about being a member of a Group in College, you have people who are there for you and vice versa! What about down the road after school!?
Some GDI say We Buy Our Friends, Ha, little do they know the Bonds that are built after College. Life long friendships are worth the effort and time!
