Lego is THE best toy in the world. It really is! If you are spending more than $50 on Lego on Toysrus.ca, they will reward you with a free $10 gift card to be used on a future purchase.
I think it's a pretty decent offer, as Lego isn't cheap and it would be very easy to spend $50. So if you were planning on buying the kids some Lego this Christmas anyway, Toysrus is a good bet.
P.S. Push your online Lego order to more than $75, and shipping would be free.
Gift card redeemable from December 27/09-January 30/10 Excludes all Lego-branded video games and toddler furniture. While they last! No Rainchecks!
