I read that bullet points have to be consistent when it comes to content and punctuation. For example, you can't mix full sentence bullet points with fragments. Is this true for hyphen points (if there is something called hyphen points)? I'm trying to write a list of shipping instructions for a friend's small online business and not sure if the below makes sense.
-Invoice must be included in the package.
-Ship via standard shipping.
(Or if I want write free shipping)
-Ship via free shipping.
-Free shipping on orders over $25.
I'm not sure id I'm punctuating the sentences above correctly, because they seem unrelated to each other and I'm mixing a full sentence with fragments.
