The Real Canadian Superstore currently has LEGO Superheroes 6862 Superman vs. Power Armor Lex on sale for $12.17 (reg.$24..99). Savings work out to be 51% off. Thanks to forum member nami for the heads up.
Some stores are still in the process of changing the shelve tags so the price label may not reflect this price yet (but it should scan at $12.17). Great price for the minifigures!
