Indeed! Apparently I too have unwittingly been growing my collection since 1991. Of course back then we just called it "buying my music".
I would show it off to that community but it's just stacked in cardboard boxes (alphabetically, I'm not an animal), not nicely curated and organized and dusted weekly in pride of place. Also, I've never counted, but it must number in the several hundred; I wouldn't want to overwhelm any fledgling enthusiasts there. ;)
The terms of this program on the Staples.com site, which servers the USA market, stipulate U.S. stores.
I would describe the recycling information at Staples.ca, which I found at https://www.staples.ca/a/content/sustainability, as no more than a collection of brochure-quality blurbs about their recycling services' availability, with no information about an incentive program; I see no mention anywhere of paying the customer for bringing in recyclable items. That's not to say that Staples.ca mayn't just be slow to update with new information. If such an incentive-based initiative is in effect at Canadian stores too, that's great news.
