To hire one of these costs £27 (this is the cost for a 3 month rental) this is yours to keep for 3 months. At the end of the 3 month period you have a decision to make. you can bring the instrument back with nothing else to pay or you can keep onto the instrument for a further 3 months.. At this point the balance left to pay is £79-£27 (£52). To keep the instrument for the second rental period it will cost a further £27 so that after 6 months if you want to buy the instrument it will cost you just £25 (£79-£27-£27) Makes sense?
