Not amazing by any means but 20% off is better than regular local retail if you want a set or two.  I picked up a few Superheroes sets for my own collection (Superman/Lex/Wonderwoman + Wolverine Chopper +Spider Cycle + Arctic Batman) and at $19.99 it's not bad at all.  Free delivery and no need to head out to a store.  So far no damaged boxes from Future Shop/Best Buy.  You might be able to price match somewhere else like Target for additional savings using Red Card or BB for their reward zone points.

 

Haven't seen Superheroes on sale for a while in CAN...and tired of TRU raising some prices before their discounts haha.

Looks like a small price error on the Technic Helicopter 9396 regularly $149.99 CAN but site shows $119.99 which is 20% off (or US price) before the actual 1 day promo discount in your cart.  So final price is $95.98, pretty good for CAN.  My first Technic purchase.  Don't know the market/demand for these but easy returns so buy first and think later right
