I sold this on Craigslist with this ad:

Small scooter. The platform is not much larger than my size 9.5 shoe.
Model A
My goal with the text was to establish the scale. Looking at the photo, you can’t tell if this is a kiddie scooter or a bigger scooter, or an adult-sized scooter.
I set the price at $4, which is what I paid for it. I figured that others were selling at $10, and a new one is $30, so those $10 scooters aren’t a good deal, at all. $4 is a good deal.
A buyer contacted me shortly, maybe a week in, and I told him the address, and instructions to just leave the money in the mailbox.
It was left exactly where it was photographed. It’s a little hidden from the street.
That’s how you can do a Porch Pickup.
You might be thinking: why not list it for free, and get rid of it faster?
I find that freebies attract too many people, sometimes. They cause too much email communications and too many flakes.
If you set a small price, you will get rid of the people looking for free things. It doesn’t really make sense, because it costs money to go somewhere to get a free item, but it works.
I had exactly one buyer, and they didn’t flake out, at all.
