J & R is THE place in the city to buy anything computer or electronic related. You usually cannot beat their prices, and they simply have the best selection, possibly because of more space, but you just can't beat it.
Cameras, computers, printers, music, DVDs, CDs, accessories, it's all here.
They also have student software in the store which can be a great help.
Sales people are very helpful. My biggest complaint is that you have to keep going up and downstairs to find what you need, sort of like Pearl Paint, but at least there are escalators!
Also - if you ever need to return anything, it's like going to an underground prison - kind of a scary experience, and they're not too happy to see you there.
Other than that, A+!
