I just realized something tonight... Suppose you wanna offer your kid Energon Optimus Prime ($60CAN). But then you realize it combines with Wing Saber ($40CAN). And Omega Sentinel ($80CAN). $180CAN of Prime fun? That's a lot of money... The toys are great, but sometimes they forget about the parents it seems. Or take Cybertron Optimus Prime ($60CAN), Leobreaker ($40) and Wing Saber ($40). That's another good chunk of money. Or the Armada Prime/Overload/Jetfire trio.
