Given that Prem clubs get approx 200 tickets for the AIs and 6Ns, I'm surprised that clubs at level 9 get that many. It's no wonder they get passed on to local sponsors who may not have any takers in their staff & so sell them on.
Fred , not sure how other Clubs operate , I normally get a list of people wanting tickets ( about 60) for each 6 Nations Home game , names are all put into a hat and drawn , people that tickets for the first game , don't go in the hat for the 2nd and so on , usually everyone gets tickets for at least one game .
