I was perusing a zinester’s website where they sell art prints and zines. They are selling unsigned copies of their latest zine for $8, but signed copies are $9.

Buyer behavior says, “Who do you think you are? Picasso? I don’t need a signature.” And they potentially don’t buy at all.

Instead, sign them all, and sell them at the higher price. then offer a combo pack of two zines for $16, and a small art print + a zine for $40.

Now you’ve given them options, and the law of averages says most of them will pick the middle one
