I bought mine on the website for each attraction got some unbelievable deals for our trip last Aug like the Universal/IOA 7 consecutive days entrance into either for the price of a 2 day ticket, so its worth checking them occasionally to see if they have any deals, tickets are mailed sometimes at no extra cost and even adding on the post to the UK made these a great deal, others like Busch you print out an ETicket that you take along with id to the attraction.
