Sold means thet have been bought - sold out means they have been bought totally and there is no ticket available.

1-- Just this year. Be in simple present tense is now: I am tired.

2-- No contradiction: all of the tickets available from now until August are sold out. August tickets are available. All does not require universal application: All the people in this room are gay does not mean that all people everywhere are gay.

Hallo all together,
my dictionary:
Once I'd bought a ticket. Unfortunately I'd sold the ticket because needing money.
As I wanted to buy another one, the tickets were sold out. Angrily I torched the box office.
The fire brigade couldn't put out the blaze. It took lots of people out and the whole office went off.
Now I'm doing time for the rest of my life. Is there anyone who wants to redeem me?
hi, hi, hi... Have fun...

[Mister Micawber]

Once I bought a ticket. No call for the past perfect.

Thanks,
the past perfect needs a direct connection, doesn't it?
---> Before I got crazy, I'd bought a ticket.
Have fun...

[Mister Micawber]

Not even there, Capablanca, since 'before' clearly orders the events:

Before I went crazy, I bought a ticket.

Past perfect is necessary when confusion otherwise results:

When I'd gone crazy, I bought a ticket.

Oh tough,

The fire brigade couldn't put out the blaze. Even they'd had to take an ice-cold shower, so they were very slow.

I'll never go crazy. Thank you.
