Ha, in the 36 years my parents have been married, my mother has never asked my dad to buy her feminine products. He wouldn't do it anyway, but that's beside the point. Hell, I can't imagine asking him to buy mine!
Going back to what was said originally about men and shopping lists, my dad does the grocery shopping for the house and he's really good about buying only what's on the list. He might throw a couple odds and ends in there somewhere, but he can go shopping without an issue.
