Whilst technically inferior, a supplementary close up adaptor will be cheaper and will allow you to see if you like the idea of macro and help you decide if you want to get a dedicated macro lens later.

Rather than the Nikon 5T which seems very expensive to me (70 on UK Amazon site) you could get a set of +1, +2 and +4 dioptre supplementary lenses to suit the filter thread of your lens.
