This past season, I did virtually all my shopping on Amazon. They make it so easy, do not they? Just when you're wanting how to estimate wholesale price know what to choose for that impossible-to-buy-for person, they appear in your email box with a very helpful reminder. If you don't like what they are suggesting, that's okay - they'll recommend products that other people liked.
It's a genius business model. They draw you farther as well as farther into their world, get more and more information about you until they realize you better than you understand yourself. Due to this smart, top-of-mind design, they've made billions.
Believe it or not, you can apply several of those same concepts to your personal direct mail marketing.

Understand your customer.
Be ubiquitous.
Put in a smile.

While your online business may well not experience the merchant of supplying music and books, you are able to still take a few pages from the Amazon playbook and see actual achievement.
