Unless you've got loads of cash you'd like to waste (which first year students apparantly love to do), then stay away from this bookstore! Books are WAAYY overpriced and although they have some cool UofT clothing, they too are overpriced as well. $50 for sweats that have the UofT logo embroidered on them? No than.. oh wait crap I bought them (as you can probably guess, I was one of the ones that went crazy in first year and bought all the UofT crap I could)
If you're looking to buy books these days, buy them online! You can buy them for at least half the price the bookstore sells it for!
The upstairs has a pretty cool computer shop but again is pretty overpriced and you can find better deals along College street.
Overall I haven't had great experiences of being ripped off while waiting an hour in line.
