Dear vendors (and all business owners, really),
When you have serious apostrophe abuse and other spelling or grammar mistakes on your website, I don't care how good your services are or how good your reviews are, I will not use you. How you portray yourself in writing in your marketing materials speaks volumes about you as a business person and your professionalism. The good news is that I now have lots of new material to show my students as examples of why good writing is so important!
A free tip: possessive pronouns and contractions and NOTHING ELSE get apostrophes. Those things that get apostrophes must have them; they are not optional! (e.g., "What Make's Us Great" is SO many miles from any semblance of correct punctuation!!!)
