Tickets for game against Eintracht Frankfurt for non-members

Hello!

I hate to do another ticket question post, but I'm in a bit of a bind here. I've planned my time in Barcelona around the game against Frankfurt, and I just saw the news that tickets will only be sold to socios. I likely cannot realistically afford the price of a membership and ticket, nor can I really justify it as this will likely be the only time I'll be in Barcelona for a long time. Therefore, I was hoping I could get some advice on what my options are.

1. Just to confirm, will tickets not be released to the general public at all? Not even the day before/of?
2. Are there any good, reasonably priced, trustworthy resellers?
3. If I did decide to cough up the money for a membership, how much would the tickets cost on top of that? As obviously I can't view ticket prices currently, not being a member.
4. Am I just cooked?

Thank you :)
