和楼主遇到类似的情况。准备9月底去，看和granada的比赛，结果在官网上每到支付页面就报错，只能在ticketmaster上买。出票后没有打印出来，但会发确认邮件过来，邮件里说用支付的信用卡和护照取票就行。Tickets can be collected from:


monday to friday, from 9 a.m. To to 5 p.m. any ticket office Blaugrana.

saturday, from 9 a.m. to 6.30 p.m. in the boulevard ticket office.

sunday, from 10 a.m. to 2 p.m. in the boulevard ticket office.

We remind you that you must show the card with which the purchase has been made and the ID card of the holder.

另外我订的时候也碰到几乎没有连座的情况，结果选了在同一排的相隔3个座位的两张。后来看到经验贴说赛前几天可能放出的票子会比较集中，因为部分会员会放弃购票，实在买不到心仪的或者到那个时候试一试吧
