I want to take a friend of mine to the final match of the season on 13th May. I'm not particularly an Everton fan, but my friend is. I know Evertonia members get a 3 day period to buy tickets before they go on general sale - I'm thinking of paying the 19.99 just to get the membership in time to buy tickets (which go on sale Monday)..I'm worried if I wait til thursday (general sale), tickets will be all sold out. Is it worth it? I'll literally never use it for anything besides buying these tickets. Also, would I need to buy 2 memberships to get the 2 tickets for us? Im not sure how it works. Do these matches generally sell out to Evertonia members? If it weren't the last game I wouldn't be so worried but I'd kick myself if I miss out!
