CHILDREN BOOKS
They go by their french name. You need to walk all the way to the back. When you enter, you would think it's only an adult clothing store.
They take credit card and charge for plastic bag. They have the best prices.
I bought 20 children books. $1 for one or 5 for $4. There is even brand new books with 20 copies. I came across mostly English and French. There was a Polish, Greek and Italian book too. My little one went found a few toys. The train figure was 2 for $1 and little people brand portable track that makes sound was only $2.
This location doesn't have other stores near by to buy more stuff. I suggest trying Fripe-Prix Renaissance (it's actually goodwill) and Dollarama too. The store are across the street from each other. They had books for $1-1.5. If you are traveling from US, then you actually save 20 percent because of the conversation.
