Absolutely agreed. You're just killing your own chance at making a sale when your grammar isn't clean and error-free.
I have a helpful little paperback that sits at the side of my desk when I write. It's called "Improve your writing from A to Z" by Ross Edwards and it is basically an alphabetical index of writing rules.
Don't know whether to use "that" or "which?" I look up either word and it has the answer. Don't know whether to use an apostrophe? I look up "apostrophe" and all the rules of usage are right there. Not sure whether I am supposed to hyphenate "third-party?" I look it up and it tells me whether I need a hyphen or not based on how I'm using the term. It's easy as dirt and I wish I had a book like this back when I was an undergrad.
Anyway, I got it from Amazon. I'm not sure what the etiquette is for links here, but you all know how to use Google anyway, so knowing the author and title should be sufficient for anyone interested in getting it.
