This is my favourite Sephora in Toronto. It is so well organized and the sales associates are so friendly. Plus, after walking by stores like Gucci, Prada, Chanel and LV - it feels good to get into a store where I can actually afford something.
I love how the sales associates aren't pushy. You are free to browse, test products and spend your time looking up reviews on your mobile device.
Their return policy is great, if something doesn't work for you, just return it within a reasonable amount of time (not sure the exact conditions). They are generous with samples, and the Beauty Insider program is appreciated (every $100 you spend, you get a mini-product, and your points are banked over time, so you don't have to spend $100 on the spot).
