Can you make a blog and store combines on here?

Hi. I'm new and trying to choose a template.... but I want my site to be a blog And a store.... that's possible with one site on here isn't it? 

Just want to make sure.

Which templates can I choose for that?

I don't know if others would agree here, but 7.0 templates have had more commerce "experience" than the 7.1 family.  The 7.0 Brine family is a good place to start looking. Avenue, one of the oldest templates, is a very strong template for bloggers, with a traditional grid layout for photographs, art work, images of products. By default,  It is not a super scrolling site, but can be very good site for shoppers.
