Answer:
A good marketing strategy for Randy would be to try to keep a base of loyal customers. This can be achieved by focusing on quality (like Raindy is doing), so that customers feel that the product satisfies their needs and beyond.
Because Randy wants to focus on wealthy, quality-seeking individuals, he should made the buying experience comfortable for every customer. Brand loyalty not only comes from the product, but also from the buying process. Loyal customers stay loyal for the whole experience.
