Piping/icing bag question?

I want to purchase this icing bag http://www.amazon.co.uk/TALA-BRANDED-ICING-BAG-NOZ/dp/B000EUKOMA/ref=dp_cp_ob_kh_title_2 because it is cheap and has good reviews but it does not come with the wide nozzle for frosting cakes, can I buy a different nozzle or will it not fit?
