Mad Lews, that's so very true.
And, in this day and age, it's very important to take the time to edit our work before publication.
There are a number publishers who do not, that's correct, do not, edit work. Yes, they format it, make it pretty with marketing, etc. Yet, they won't edit the story, even for spelling or punctuation. They'll even state this in their submission guidelines.
It can make for some frusterating reading after a book has been purchased.
