I don't think there's much extra money to be milked by the Phoenix from season-ticket holders, club members, attending fans, sofa fans or the wider NZ population but a Supporters Scheme to buy a 'share' in the Phoenix is probably the best method, rather than this give-a-little approach.
This is something I could get behind.
If you got to own 0.00000000000001% (random guess number) per dollar spent then I'd be keen as punch, as even though you wouldn't make any money out of it, you would be able to be proud as punch that you own your little slice of the club.
It's kind of a clever way to get distance supporters behind the club and garner interest. Give you a little reason to give a shark, and then you aren't donating money to watch them lose.
It does seem like a slap int he face when the club members aren't included in the family list "players, coaches, officials, and corporate partners" though. but thats just sour grapes, if this helps the club stay alive then fudge it, more power to them.
