I can't remember how many points but all the big AA games needed them and I don't think they got to the point of allowing you to buy extras. You can also purchase from Viagogo from season ticket holders (this is pretty much the only way you can really choose your seat!), so if I'm taking someone, I usually get the two for myself and my son and then try and find two nearby from the ones available on Viagogo. The group stage european games just went onsale - it wasn't staged by points. I did, early on in the season, take the risk of waiting to get four together (can't remember which match) and there was very little left, and no concessions for the kids. We ended the season with 68 points - got FA Cup semi-final tickets and luckily got two extras when the FA found another couple of hundred tickets down the back of the sofa. However, we didn't get FA Cup Final or Champions League tickets - those all went to season ticket holders.
