Not to be a dick but you're right, this has been posted 100 times, if not undoubtedly thousands more. Hell, it's probably posted once every other day here.

The best way to get tickets is to become a member and try and catch a home game. There are 2 members' sales a year (as well as additional members sales for returned tickets and such 2-3 weeks before each match, but they're very limited, if at all). Very occasionally a match will go through all the additional stages and then get to general sale, but again, they're very limited seats, if any.

Either that, or become a member and get on the auto cup scheme for one of the cup competitions. But you've missed it for this year I think, but there might still be tickets available, I'm not sure. Best time to get these tickets is like 7-8 weeks ago when they're released.

You won't catch an away match. Unless you buy a ticket in the home section. You just won't. Away tickets are like golddust and reserved pretty much only for those who go to every single away match.
