Take note that ticket reservation is different from ticket pre-selling.
Ticket reservation is until Nov 13. That mean you can only reserve your tickets until that day. We save tickets for those who requested it.
Ticket pre-selling is another thing. We sell tickets before the day of the event itself so you guys get a discount. You can buy Php90 tickets until Nov 25. Whether you have reserved a ticket or not, if you buy during the Pre-sale period, you'll only pay Php90 instead of Php100.
