I got the stuff and really like it, particularly the hat, sticker and keyring. Most of this is $ well spent for the club, as it makes Membership more visible. It's really very cost-effective marketing, and I doubt opting out of receiving it would really do much for the club.
Question is though I got a family pass... do you only get 1 set, or 4?
Also... nothing the club can do about this, but lucky I got it, as Australia Post just left it hanging 90% out of my mailbox, even though it says "Signature Required on Delivery."
Next year maybe there can be a Pick Up option, as I know I'll probably never get a parcel delivered cleanly.
