Universal Studios -- Any multi-day non-expiring tickets?

[AmyAnne]

Last time I bought Universal Studios tickets, I got them at Costco. They were great -- three days that did not expire 14 days from first use, so we were able to use two days one trip and the third day on a trip the next year. Now, the only multi-day tickets I can find expire 14 days from the first use -- which really does not help, since we are only planning one day at Universal during the upcoming trip.

Anyone know where I can find tickets for multiple days that do not expire 14 days after the first use?
