The ticketing is game specific, but in general the rules are fairly simple (and fair in my opinion). It is one ticket per member. If you wish to purchase more than one ticket you need more than one membership number.

The only time you are able to buy more than 1 ticket is for when tickets go on general sale, or for rare circumstances (such as the European Games this season) where it's not general sale but members can buy tickets for non-members. This applies to online and over the phone as I bought Moscow tickets (2 member 2 non member) the day they went on sale over the phone.

 Given the limited number of Everton tickets still available, I think it's highly unlikely you will be able to buy more than one ticket.

I went to the ticket office before the Moscow game on Tuesday to buy a ticket for the Everton game; the woman behind the counter tells me that I can only purchase one ticket, and yet online, as I've said before, I can purchase upto 9? This is really confusing because it means I'm always thinking that someone is going to ask me for another membership card for the other person. Does anyone else find this annoying aswell? I didn't buy the one ticket in the end because I'm waiting to see if they go on sale online nearer to the time of the game
