I had been looking at getting the Octonauts Octopod Playset for my 5 year old son, but a bit pricey with an RRP of $89. Kmart has it on special for $55 commencing Thursday 27 November in store only, works out as a 38% discount.
Currently on special at Target for $64 (until tomorrow) here
There is also another Octonauts playset on sale for $55 - Octonauts Deep Sea Adventure Octo-Lab, RRP of $90, currently on special at Target for $65 here
