Important: Promotion CODE.

Admin can give promotion to friends, family as long as they have a promotion code.

or special newsletter promotion code.

and when checking out, promotion code is entered, it can give discount in percentage (5%) or discount in price ($5) or free items!



All this are business marketing skills.! 

It will be added on the next big version. I wanted to do it for v0.7 but there are to many differn't types of discounts you can have. I need to research what are the most useful.
