Wal-Mart Canada stores now has their exclusive LEGO Star Wars 7868 Mace Windu’s Jedi Starfighter on sale for $40 (reg.$49.99). Savings works out to be 20% off. Note that this is most likely a discontinued set as LEGO Shop has removed it completely.
LEGO Cars, Harry Potter and Pirates of the Carribean theme sets are also still available for 30% off (from their boxing week sale).
