If you must sell to a man and a woman together, how can you keep them both engaged in the selling process?

Retailers might face several obstacles when applying the concepts from "Why We Buy". One potential obstacle could be the difficulty in understanding and implementing the diverse shopping behaviors of different customer groups. Overcoming this requires careful observation and analysis of customer behavior in the store. Another challenge could be the cost and time involved in modifying the store layout or strategies based on the insights from the book. Retailers can overcome this by prioritizing changes that would have the most significant impact on customer experience and sales. Lastly, resistance to change from staff could be an obstacle. This can be overcome by training and involving the staff in the change process.

A startup retail business can use the key topics covered in "Why We Buy" to grow by understanding and implementing the insights about customer behaviors. The book provides valuable information on how different groups of people shop differently and what they want from their shopping experience. By understanding these behaviors, a startup can tailor their store layout, product placement, and marketing strategies to cater to these specific customer groups. This can lead to a personalized shopping experience for each customer, potentially increasing customer satisfaction and sales.
