Hi, this is funny. That website - http://www.fashion-mart.biz/ - is one of my sites! It says "A Division of PromMart.com" in the header.
But it is not the Estorenow template. It is Alien Stemware, one of several templates I'm using/tesing on that site.
You can see it and the real Estorenow template here, and there will be a link to the downloads: http://(sorry, site offline)/zc150/
The Alien Stemware template may be hard to work with. I just turned off my right column and banners (tried this once before) and it doesn't work right. It's not like most free templates where you can just turn off one or both columns from the admin and it still works. I intend not to mess with this template while I have it on my site; if I continue using it will use as is out of the box.
If I needed to turn off the right column, I might look for another template.
Or contact the designer by email. I've been in contact him before when I was using/testing his S E X Y template contribution on this site. You can get to his site by the link at the bottom of my Alient Stemware site.
Yes, on most templates you can set your homepage to be one column, then maybe your categories to be three columns, and maybe the product page to two columns with it on the right or left. This assumes that the chosen template is within the core zencart framework. Some templates go beyond that, complicating things.
Personally, unless one has some real design talent (I don't), my recommendation would be not to mess with a template, as the designer probably did a better job than I/we could.
Hope this helped.
BTW, I've tested Estorenow template (and many, many templates) and it is a very nice template. Don't know if it works on 1.5 cart, though.
