Their quality's good but their deals can be hit or miss. They do not offer many coupon codes and even though I reside in Canada, sometime it's still cheaper to buy off of US sites.
They do not offer price match from sites in the US that have canadian currency and they will look to see whether you are a Canadian customer. I think they think that if you are Canadian and with out limited selection up here, we are getting a better deal from them even if they jack up their price. They jack-up certain prices due to importing however I don't think all of their prices are justified. I bought a marc jacobs scarf from
Neiman Marcus for $112.00 total with shipping, tax/customs included while they still wouldn't price match the same scarf. Ssense's "sale" price was $165 (without tax).
I would like to support Canadian businesses but only if they keep up with competition. So yes, depending on where you live and where they set their original price, you can get deals from them.
