The Sham of how the 31k is allocated...

Could someone please enlighten me?
So we have 31k for the final, the same as the semi.
We have around 31k season ticket holders.
Yet its sold out before its go to my allocation of around 3,300.
How can this be?
Supporters clubs getting bucket loads? People buying more than one?
Now personally, a girl I know in londong has got me club wembley tickets through her work (Which to be honest I don't agree with), but some of my mates and dad are left out. I'd also planned on swapping the club wembley ticket, as I want to SING, WEAR MY SHIRT, AND GENERALLY BACK MY TEAM IN an FA cup final. Although third tier in one of the corners was a JOKE for the Semi by the way, all sat down in silence, so I pissed off and we went and stood elsewhere.
