Check off one more experience from the list: a multi-family yard sale.
It's fascinating to see the pros in action. We said it started at 9am, the early birds were poking around shortly after 8am. You put a rock bottom price on something, bargaining starts at half of that. One gentleman mysteriously put forth a closed fist containing his offer for a $2 cake pan, slowly opened it to reveal a single nickel. And the biggest bartering is always for the last quarter.
Despite the overnight rain, it stayed dry and we had a constant stream of people until about 2pm. When all was done, the haul was over $300 and the remainder needed just one full truck trip to the Goodwill store.
