Here are a few I know that are around here.

Creepy Thomas O. has an anthology on Amazon.

You can go for Humper-Monkey's Ghost Story. It's a pretty good book. Only problem I have is that it's a bit unpolished (some mechanical errors) and it's basically identical to the version here (except for the typos/issues we've corrected).

You can get the novel "Penpal" which has an introduction and is a bit polished up from the original.

There's also the We Go Bump anthology which features authors from this site or even I Go Bump which has some of the Founder of this wiki's eldritch works.
