Hi Ben,
Welcome to the site - if your looking to buy tickets for the upcoming home game (25 Jan) a good place to start is letting people know if you have a Palace membership / ticket account number - if you have one it makes it a lot easier for the people selling the ticket(s) to transfer it / to trust that your not Chelsea (Away Club) supporters trying to get any ticket for the game & because you weren't able to get tickets from the away allocation are OK with sitting in the home end -
I think its quite unlikely that anyone on here will sell you tickets with no site history (as your a new member) & if you have no membership / ticket account number, obviously I don't speak for everyone but that's certainly the general scenario.
The club box office will advise you on any available memberships (+costs) and sometimes have tickets returned to them for resale, as its only 2 of you the chances of getting 2 tickets close to each other I would have thought would be pretty good, especially as the game is on a Sunday
