We live in an affluent area, so we have some pretty good trash and secondhand things. We have a pair of trash-picked Waterford crystal goblets, which we keep in a china cabinet that, with its matching table and chairs, we inherited from a family friend who was cleaning out her late mother's stuff about when we moved in.
Shout out to the local Buy Nothing group for taking many of the things thrift stores can't. Someone else mentioned half-eaten pizzas and cakes. I've given and received excess foods from various delivery services, including stuff that went to the wrong house and can't go back. Gardeners offer excess crops, seeds, divisions, and cuttings. I'm sensitive to fragrances and not sure what all I'm allergic to, so when a shampoo, lotion, cleaning product, or some such makes me sneeze or itch, I can give the rest to a neighbor who's happy to have it.
Our BN group also has a lending library, in which all kinds of things make the rounds: tools, folding tables and chairs, small appliances, and things like kid-sized snow gear (only needed for travel out of our mild climate) and a travel case for flying with a car seat. I once asked to "borrow," and received, a much smaller quantity of Shoe Goo (adhesive) than comes in one tube. I made my repair and returned what remained.
We even exchange services and skills. One member is a notary. I helped someone mend a favorite bag that was a little too well-loved. Neighbors have helped others transport larger furniture that's given. Occasionally, someone will help a neighbor is moving out to list their excess stuff for the group.
I think it was either the blog or this forum that introduced me to the idea of "storing stuff on Craigslist." It's not an exaggeration that I store stuff on Buy Nothing. Knowing that I can reach into this network and come out with all kinds of things and even assistance saves me money, space, and stress.
