VBA Tutorial `

I have been googling and I learned everything for free from www.ozgrid.com
I understand formulas pretty well, I can 'nest' them correctly, and I have an understanding of all the formulas listed on this page: {url}
So now I understand of formulas and excel, so I want to go to the next level. Macros.
As from the research I have already done, I am starting to understand the structure of how to write the code, but I am stuck as to what to look at next.

So far I have tried to avoid buying any books or paying for the knowledge.

Im looking for a good tutorial on how to setup the structure of the macro, what to write and when.
