I wouldn't go with starch on casual shirts. For "dress" shirts, I always go with light startch on broadcloth, poplin and Oxford cloth shirts, just so I could wear them more than once if I wanted to. I also launder my best shirts at home, and sometimes will use a dusting of spray starch on collars and cuffs. I'm not totally convinced that using starch will reduce the life of your shirts, at least not noticeably.
