Probably not, unless I was home schooling, or if there was a topic my child had a high degree of interest in that either wasn’t being covered in school or wasn’t being deeply covered. Or a area that they are struggling in.
A lot of kids don’t enjoy course work, getting them to do more (unless they showed a high interest in it), is probably not a battle most parents are going to want, let alone pay extra for. Of course we all want resources if our kids are struggling with a subject.
