Uggh, arguing about commas. First off, it's not a clause unless it has a subject and predicate (see here); this is a phrase since it's not a complete thought. New phrases introduced by conjunctions such as "and", "or", or "but" do not get commas, unless you're joining together three or more. For example, "The 3-year old cannot read but can tie her shoes." should not have a comma. On the other hand, you do need a comma in "The 3-year old cannot read, but she can tie her shoes."
