A Standing Order for Kids' Outgrown Clothes

The idea

My kid grows out of clothes every few months and I end up with bags of stuff sitting in the closet because I never get around to selling or donating them. I want a service where you set up a recurring pickup, drop the outgrown stuff in a bin by the door, and it goes straight to a consignment shop or another family on a list who needs that size next. No listing photos, no meetups, just a scheduled swap that happens in the background.
