Is the rental car discount through FMCA worth it?

[gatripsters]

At this point in time, we do not travel enough to justify buying a toad, so we usually rent cars when we arrive at our destination.  Today, for the first time, I used the FMCA discount at Enterprise. Attached are receipts with and without the FMCA discount.  Apparently, if you do not have a promo code, Enterprise puts their own in.  So was it worth using the FMCA discount?  Apparently not at Enterprise.  You get a discount regardless of whether or not you pay membership fees to an organization.  Just an observation.
