Is it worth it joining an honor society? Hello all.

I'm of course overanalyzing everything and making myself nervous about my applications.  

My question is, should I shell out the $95 to join Golden Key International Honors Society?

I don't have any awards that I've won to add to my CV.  I'm currently finishing my M.A. in history at a Cal State school where I have a 3.94 GPA and scored 170 v, 156 q, 5.5 essay on GRE.  I'm applying to Ivies, and feel somewhat hopeless.  Undergrad cumulative was 3.05, with 3.51 at my alma mater once I finally got my head on straight.  I think my CV is the weakest aspect of my application.
