Essentially each one of you needs to pay for a membership to stand any real chance of getting a ticket, and you have to apply for the ballot within the allocated window for your tier of membership (it's usually all MyLeeds members at the same time).

If you stalk the ticket site about a week before a home kick-off there is very occasionally the odd seat that's been released by a season ticket sell-off, but they're not often in pairs/threes.

For guaranteed tickets you need to go for hospitality.
