Kmart now have RPMs, both Minivehicles and Battlechargers. Saw them at the Sunnybank store. Single pack MVs (wave 1 and 2) $9, and I think the Double packs (wave 1 and 2) were $18. The BCs were $23 each.
They also restocked their Legends, including more of wave 1 (with Optimus, which I was having trouble finding a couple weeks ago).
