If you have to pay sipping on it, it will be more expensive than if you buy it locally from a high priced retailer.
If you're planning on buying several boxes, try one of the banner advertisers above, like CanadaAmmo.
Even then, Canadian Tire and Wal Mart are hard to beat price wise.
By the way, driving all over town or the lower mainland, looking to save a few bucks might be fun but fuel is expensive as well. I have to shake my head over someone that drives for a couple of hours to save a loonie or toonie on some item.
