soulchiefAn online _Canadian_store, probably yes. That's because they're local and they don't have to pay to ship it across a border. I doubt you will find a US online store that will ship it to Canada for cheaper (or significantly cheaper).
MarkWell, US online shops aren't allowed to ship MTG boosters to Canada (which sucks cause I've seen some good clearance sales every now and then). Hopefully massdrop can find a Canadian MTG distributor so the shipping cost is less (I ordered 2 RnR boxes from the last one since it was a good price for that one).
