This is hard trying to explain what I'm looking for but here goes.

I'm looking for some free wordpress themes that have a ecommerce
style to them with the larger buttons.

I know some of these are special made but these come close to
what I'm looking

Or a site that has previews for the themes instead
of having to click on each one.

I'll take it that you're not advertising. Moved to Website Help.
