This is probably one of the best Dollaramas in the downtown core. It is also one of - if not the busiest locations.
The pro is that there is always new stock, so if you frequent dollar stores, you will find new merchandise is brought out here very all the time. Come back in 2 days, and there will likely be several new finds.
The con is that good stuff sells out fast - you can't hesitate,and hope to find it again next time you're there.
Expect lineups; avoid standing in line behind anyone buying glassware - as that takes FOREvER for the cashiers wrap.
