So don't quote costs per month. If it's the only event they play in, the additional cost for a four player team is around Â£ 44. Next season it will be up to Â£ 108 if rates don't go up. If a club is thinking of entering and using general club funds to pay for it, it needs to know these costs. The same applies if it's a group of friends having a whip round.
