When I was in Seattle for an internship about a decade ago, I would get books and other sortable items thrown in with my Amazon Fresh deliveries— they would show up in the same rugged plastic tote as the pantry items, and the tote would be picked up again the next day. It was a great system.

Especially with the recent news that a lot of what we thought was recyclable really isn't. I presume that clean brown corrugated is still OK, but I don't know that for sure.

oh it is "recyclable", just (for several materials) takes more energy to recycle it than toss it in a landfill. You get to feel good that cardboard gets a "new life", instead of a new one (which extracts more carbon from the atmosphere) being created, we can burn more CO2 to have a second truck travel down your street to pick up renewable cardboard and haul it around town till it eventually gets cleaned and processed (at the cost of even more energy).
