I love thrift shops, charity shops, yard sales, flea markets, car boot sales. In The Netherlands, on the King's birthday, people are allowed to put things out in front of their houses, to sell. Then they need to wait a year. Albuquerque has an ordinance that says a family can have a garage sale or yard sale twice a year. Most people never do, and some have one nearly every week, so it all evens out.
I have some wonderful things with good stories, bought off a little table at a casual local fair at a hill fort in Cambridgeshire in 1979. From a yard sale in Colorado Springs in 1970, I got a Chinese Checkers board made of wood, with a set of marbles I still have. But even the names of the places are exotic and collectible: Wandlebury. Colorado Springs (called more locally "C-Springs" or "the Springs").
When digital cameras came along, I bought fewer things and spent less money for other people's used treasures. As museums and ever-changing collections, they are wonderous. Unlike "real museums," if you love something, you might be able to buy it! But you can probably pick it up and examine it, even if you don't take it home.
