It's a US store chain, it's not in Canada. I'll post a link to their locations. There are a few stores in Canada called Half Price Books but I believe they're unrelated to the US chain talked about here. From what I can find the US chain is 41 years old, yet the small Canadian one has been around since 1992.

In Canada we don't have any used stores that nice besides independents, most used store chains I know of are thrift stores and it's kind of a rule that everything has to be disorganized or using horrible fixtures that look pulled from a dumpster. Finding actual independent used bookstores is hard enough out here, seeing ones with displays as nice as a collector's personal display is rare.
