[Canada] Zellers LEGO Sale: 20% off on ALL Themes

It appears that Zellers 20% off LEGO Sale on select themes actually applies to ALL LEGO! The sale signs in the store shows 20% off ALL LEGO Alien Conquest, Cars and Hero Factory. However, LEGO sets from other themes will scan at 20% off as well. Thanks to forum member Joseywales for the heads up.
