How illiterate have we become?

Case in point: This ad on a literary site has a glaring grammatical error. Is it as obvious and irritating for you as it is for me?

Did it scream out at you? Has the dumbing down of America made everyone so illiterate? TV hasn't helped. It teaches bad grammar in commercials, in sitcoms, in movies, and on talk shows. At least talk shows have an excuse: No writers. 

Does it bother you as much as it bugs me? Here it is: "soon Mr. Hudson and her comes up with" See it? Mr. Hudson and her comes --  Really? The "her" should be "she" as a subject not an object, then "comes" should be "come", for example she comes over or they come over.  AND not OR, that's key there.  That's in the lead, a tidbit  to entice potential readers. I can't imagine how irritating the book would be for a truly educated reader. Writers who failed grammar need to have an editor who aced it.
