^ Yeah, that's exactly what the offer was, Beantown. If you bought a ticket to the game against Adelaide, they had a stall set up where you could buy a membership after the game and would put the value of the ticket towards your membership.
I.e., you bought a Silver ticket at $60, think "gee, this basketball caper is a bit of alright, I'd like some more", buy a Silver Membership at ... I think it's $429, then they deduct the $60 you paid for the ticket away from the membership. So you get on board for $369.
No difference in cost for the club or patron and you get a try-before-you-buy.
