Well, if you can find something else to pair with it to make up the $10 minimum purchase, then
Uptown Local might be worth it for you since there's two Young Wizards short stories in there.
If the value-for-money ratio isn't quite right at those proportions, then you can read the entirety of the 3rd novel in the spin-off "Feline Wizards" series,
The Big Meow, for
free on the website, where it was originally a paid subscriber project (that got seriously derailed, but finally completed early this year).
