one man's gewgaw is another man's gewgaw

I've managed one garage sale before. I was — 13, 14?; I was not in public school. I did it for a Personal Progress merit (it's a thing for Mormon girls 12-18); the proceeds went to the Ward Mission Fund. The proceeds totalled between $50 and $60.
   I don't remember how long it took me to prepare. I know I went through a whole bunch o' junk and put it on display in the garage.
   Note: I didn't actually think that any of it was junk. I had tchotchkes disease.

Here are the bits I remember.

• I made my own flier for it.

• It took place in the garage.

• I sold a teddy bear (in a beautiful-red tutu) that I apparently didn't really want to sell: afterwards I lamented her sale.

• I wanted a lot of money for a ring display case and no one wanted to pay that for it. Its exterior was chipped, not just a bit. Its interior pillow was dingy.
   I was sure it was precious.
   I'd bought it at a neighbor's garage sale a few years before. It was the first and one of the only things I've ever acquired via yard sale.

• I sold a Nintendo game for $5; when an interested kid saw it and he asked how much it was and I said something like a dollar. His derisive whoop must have embarrassed his mother because she said "it must be worth more than that" and insisted he give me $5 for it.

Tomorrow I'm going to have my second garage sale ever.
   This one I won't have to make fliers for: the street we live on has a well-known annual sale. Supposedly someone puts it in the paper — the newspaper. (I don't think I'd ever have one if I had to do my own marketing.)

I've tried to price things so that they'll sell. I don't frequent yard sales, so I have little market exposure to help me set prices. I've probably set some things too high (again), and perhaps a few things too low. (It would be convenient if there were no such thing as "priced too low to sell"; the psychology of pricing isn't so easy.)
   I don't have a goal, but I suspect I'll be disappointed if I make less than $100. I plan to put the proceeds toward the purchase of a food processor.
