Can I remove a column from my page template?

Hi,

I’m in the process of setting up my blog at http://www.accessoryfetish.com.

I really like the 3 column theme for most of the site. I’ve signed up as an ebay affiliate and want to have listings automatically populate. Problem is…the center column is too narrow for the content to fit.

Is there a way to create a new template with only the left column, and the center and right column combined into one?

Thanks!
