Budget golf "membership"?

Hello all,

https://www.eagleglenplayersclub.com/join-club

I played this course today and saw this offer. A normal, weekend daytime round costs about $140 USD and is hard to book.

this deal, if my math is right and interpretation is right, is $349 for 5 free rounds (book any time outside certain holidays) and you can book 3 weeks out (beating out the general population by about 11 days). which comes out to about $70 a round.

I don't understand the $50 range key, and the other perks are just "bonuses" to me but the $70 a round seems like a no brainer unless I'm reading it wrong. I don't think Id mind playing the same course 5 times a year at all.

thoughts?
