Your blog can be more than just a diary of posts, it can be a webstore as well.
You can use your blog to sell your products as well as a traditional website.
You can have blue underlined buy link such as :
Add to Cart
or
One Click Buy Now
or shopping cart buttons such as:
And the beauty of this is that you don’t need a webmaster!
So with your blog, you can post your ideas, AND post links for people to purchase your stuff.
I love blogs!
