Im not quite sure when the sale ends or when it starts, but in the TRU “Big Book” catalog visible online here at toysrus.com, you will find that Battle Of Metru Nui is $10.00 USD off the original price. You will also find VISORAK for only $5.99! This is quite possibly the best time to get a full set or some spare parts.

…I apologize as it seems the links are not working properly.
