Hi,
Brand..brand..brand. People go for quality brand. What are the top brand in kitchen appliances. I worked in a retail industry for almost 40yrs and I can tell you that persons go for brand, features and benefits.
What can the product do for them? How will it stand up in the market? What is the life span ? Are you only giving them the manufacturers warranty or are you able to sell them an extended warranty with the product?
You must do your research on the products so you know with confidence that the product can stand up to what you say it can do for them.
You are going to have different types of clients and depending on their needs. You should know say for instance: is a GE product more efficient than a Whirlpool or Frigidaire etc.. What is the manufacturers warranty on rust?.
Hope this was helpful, you may schedule a call if you wish to discuss further.
