I only wish I could invest in the monthly fee to join this club though.

If I was in the business of running a coupon blog or a WordPress News blog (I had one in the past) I would of made the investment into this club to dish out discounts to my followers.
What I would tell you know is to try to find blogs online who are sharing discount codes because they might be members of this club.
