The Deck Box (Halifax)
6299 Quinpool Road, Halifax, NS, Canada, B3L 1A4
Wonderful store specializing in TCGs in general and Magic specifically. Extensive collection of singles for sale, amazing prize structuring for events (of which there are several per week, spanning at least 5 formats), gives good value on trades, also sells any kind of accessory you could want - sleeves, dice, binders, boxes - you name it.
Extremely friendly and knowledgeable staff, too. Definitely worth checking out if you're in the Halifax area! :)
