Besides the Zellers deal on the Night Raven, I have come across a couple of other good deals. These are online, and may be US only, but I figured I'd throw em out there anyway.
TRU has the MARS Troopers three packs online for $12.86. I know a Canadian store had these actually on the shelves on clearance, but these were only available online in the States, and offer a good deal to do some troop-building.
Wal-Mart has rollbacked the PIT to $80.
And last but not least:
K-Mart has the PIT for $56 online!
