The main business of Mument, is to sell maternal and infant products. It is a one- stop store, where customers can find baby and children’s items from new-born until nearly 12 years old, Mument has a membership system, which means customer can deposit $500, then enjoy 15% off for each single shopping time, or use a scorecard, with one point equal to $1. getting 15% off when they reach 300 points.. The aims of the research were to improve sales and selling skills, and to develop better marketing methods. The questions for Mument are how to gain better sales and select effective marketing methods. For this research, I have selected quantitative methods, and use a questionnaire to get the primary research results. 18% of customers find a long wait for their order unacceptable, 30% of customers think Mument sales-people lack professional information, and find having only one sales-person in the store at weekends insufficient. 64% customers know about mother and baby product information through friends, and 58% customers know about Mument from friends. Most member’s babies’ birthdays are in April, May, September and October. I recommend that the owner analyse what kind of products customers require frequently, and order these before they ask, have a longer training time to allow sales-persons to acquire professional information, and have sales promotions at specific times.
