As of Sunday afternoon (21st March) the following KNEX amusement park items are all half price at Toysrus. I bought the complete set of four yesterday in the Norwich store, "saving £60".

Only the Octopus Whirl is in stock online unfortunately at the moment but if this is the one you want, then great. If not, try to get to your nearest store - good luck!
