. . . aaannnd here's a funny yard sale story. I found a cute pair of shoes (with heels, AND with real tread!) marked "$1" a friend's yard sale. These shoes come with some local history; they've belonged to a friend of that friend, someone who we all admire as a fashionista, and yet the shoes don't seem to even have been worn. Clearly a good deal.
But the deal got even sweeter when my friend who was selling them looked at me holding out my dollar and said, "Nah, you can take them for free. But you have to take this Chia Pet, too."
It reminds me of Amy Dacyczyn (author of the Tightwad Gazette) describing a yard sale she held "at which we gave away our entire collection of Englebert Humperdink's Greatest Hits, free with every purchase."
FYI, although the cost of yard sales shoes varies a lot from yard to yard, I've found around here that if I just wait until I come across shoes I like that go for $1or $2, I can still keep my closest fully stocked -- way too full, even.
The exception is boys' and mens' shoes. For a few years, I was willing to pay as much as $5 for my sons' shoes. Nowadays, I can't find any shoes that my teenage boys like, so they buy shoes with their dad at real stores.
