Just signed my boy up for soccer yesterday (u6's), $120 - but $20 of that gets refunded at the end of the season if you volunteer for stuff like coach/manager/canteen etc. and then $7 per game. Still has most of his kit from last year, got him some new boots though, all sizes only $20 through the club which is cheap (includes trophy and end of season party at the end of the year too gratlog, and they've just built a new clubhouse,
... have to pay for our photos though).
Of course he also has swimming lessons at about $12/w (runs most of the year), and Tennis $7/w during the school terms... so it all adds up.
My youngest turns 3 in another month, he already does swimming too, but will have to start him on other sports in another year or so,
