Different blocks of microdata on one page?

Question

Search Engine Optimization

Hello! I have Product markup in the body of the site: name, price, etc. The address and phone number of the organization are indicated in the footer of the site, I took this information into the localbusiness block. The question is how this information will be displayed, will these blocks conflict and what is the priority for displaying information? And in general, is it necessary to do this, or is it enough to transfer information about the company to the "contacts" page and write the microdata there separately?
