The best offer I have seen is from the Universal Studios website for 7 unlimited days for both parks at US$94.99 + tax. We will be taking advantage of this one if I don't see anything else.
Purchasing your tickets at www.universalorlando.com and choosing kiosk pick-up is probably your best bet. You can also use airmiles points if you've got them. I've found that CAA is more expensive than purchasing them online.
I just cashed in a little over 3600 points for 5 adult 2-park unlimited tickets We were going to get 5 1 day/2 parks tickets....was going to cost us around $600 Canadian
