I saw OOTP in Imax and was impressed, of course, with all the goods they were selling along with the popcorn, candy and soda....Seriously, all the imax theatres seem to have exclusive deals to sell merchandise that you certainly could not purchase in an ordinary cinema/theatre....But the seats are so uncomfortable....I will see HBP in Imax and regular if only to buy up the trading cards in collectible tins or whatever goods they will be selling! I like my paraphenalia that is for sure....
