Be creative in your style and presentation manner. Be sincere about your desire to help the customer first, and earn the commission second. Be direct in your communication. Answer all questions. Don't patronize the prospect.
People like to buy from friends.
People love to laugh. Making your prospect laugh is a great way to establish common ground and rapport. When in doubt, sell the prospect for her reasons, not yours. Don't be afraid to ask for the sale each time. No perceived difference, no sale.
