A Haunting Homicide: Halloween Cozy Mystery Boxed Set is a collection of four "Cozy" mysteries with paranormal tie-ins. Three of the four are the first in their specific series, the fourth is the third in its series. They all have an autumn/Halloween tie-in. They are all published by Gemma Halliday and distributed by Smashwords.
The collection is priced at 99 cents. Each individual story is priced at $4.99, and they are all still available, individually, at that price.
I have not read these particular stories, but Gemma Halliday is a known quantity in this field. If you're interested in this sub-genre, this might be a good deal.
