This is basic tenet of all economic activity. You purchase input materials, add value to them, then sell them at a higher price. Let me give you some examples.

You run a used car lot. You buy used cars at auction, then sell them on your lot. The value you add: you found cars and brought them together in one place. Not too much value added there.

Instead, you buy cars at auction. You get them really cheap because they need some minor repair. You make repairs and clean cars up. The value you add: in addition to finding cars, you add value of your repair and clean-up labor. Much more added value here.

Another example: You join an affiliate program to sell paper products on your web site. The value you add: you put a banner on your web site. You get a 5% commission on any sales.

Instead, you buy paper products wholesale and sell them on your web site. The value you add: you maintain an inventory and fill orders. You get a 40% markup on any sales.

Instead, you buy raw paper. With paper, you manufacture envelopes, stationery, greeting cards, scrap books, etc. The value you add: in addition to maintaining an inventory and filling orders, you added value of your manufacturing labor. You get a 90% profit on any sales.

In introduction to ebook Ezine Power, I reveal that publishing an ezine can be a business that provides you with a moderate income. What do I mean by "moderate" income?

You earn income by selling advertising in your ezine. Just to get a rough idea, let's say you charge about $5 per 1000 subscribers, you have 50,000 subscribers, and you publish two issues each month with eight ads in each issue. This earns you $48,000.00 per year.

That's just a rough idea. Ezines charge anywhere between free and $10 or more per 1000 subscribers for advertising. Some ezines have subscriber bases in millions, and publish daily. You decide how much income you want by choosing subject and quality of your ezine.

What if you can't sell all your advertising space? You don't have to. You can join one or more affiliate programs and run your own ads in your unsold space. Then instead of earning income by selling advertising, you earn commissions on affiliate sales.

What if you don't like to write? You don't have to. There are dozens of groups that you can join that will fill your email box with fresh free content every day. But I don't recommend using this material because many other ezines will be using those same articles.
