Hey,

This has a broad range of answers and some fit someone better than others. In my experience, I have noticed that I tend to buy from someone who I trust because there is a commonality. If they can express the reason for buying the product and you trust that there is a benefit for your life, then purchase it. If the salesperson is showing you WHAT the product does/is and tells you WHY they are different, you're going to naturally feel that you are being SOLD something and apprehensive to buy.

If they can provide why you need to buy this product/service and how they are different from their competitors, then that should be more effective than boasting about their service.

good luck
