Brake pad help

so it's getting to the point that at almost any time i press down on my brakes... it squeeks.. so I need to order new brake pads.. this is my first time doing this -- does anyone know where I can get a good deal on some? My friend is going to teach me how to install them, all I need is just a link to some place I can order em from... Thanks!
