Aromamora PLC is a company which sells essential oils to Aromatherapists,
Health Shops, Chemists and other mass users of essential oils. Every month,
details of sales to these customers are gathered together into a Sales

from this file showing the quantity (in millilitres) and value of the
essential oils purchased by each customer.
