I usually snag all the free cozy mysteries I find that come out on Kindle (I even have one called "Lye in Wait" where the protagonist is a soaper.)
There are often multibook "boxed" sets by the same author and usually they're free for a week or two. I tend to enjoy a series because you get to know the protagonist, which to me makes it more fun. I don't like violence or "gritty", so if the books start trending that way, I usually abandon them.
If you use a Kindle, I can give you a list of cozy authors I like, but I don't know how many are available in print if you don't use a Kindle. Just let me know if you're interested.
