I made an "oops" re:discounted tickets!

I went online today to purchase my discounted park tickets for the princess half and it says "Advanced tickets purchase for this even has ended. Please visit the Welcome Center at ESPN Wide World of Sports Complex when you arrive at the Walt Disney World® Resort for on-site options."

Am I doomed? can you purchase the discounted tickets onsite??

This hasn't happened to anyone out there?
