To be fair I’ve done it both ways, and both were a success at the time.

Many years back I did a collaborative yardsale with college friends when people were moving out of town. The goal was essentially to get rid of everything and hopefully cover the cost of beer we drank that day. It was as much a chill day-drinking event w/music as it was a yardsale.

As I get older and own more valuable things, I’ve accumulated a LOT of stuff that I eventually realize I don’t really need. This results in piles of stuff I’m “planning to sell” but I kinda hate taking the time to deal with eBay. For larger items I’ll make time to meet someone from CL/FB marketplace if it will free a bunch of room and recoup some minimum cost (say $100, but everyone will have a different threshold). Eventually I realized these piles are perfect for an annual yardsale, so that’s what I do now. In my older years I get more satisfaction from this (minimally) disciplined approach, so I figured it’s worth sharing for people who are newer to it.
