Make the middle wider

I have setup NiagaraIceWineShop.com so that all the boxes we're currently using are shown on the left side.
This allowed me to make those boxes a little wider but now I have extra room on the right.
Is it possible to make the "middle" wider? There is no setting for this on the page where I changed the width of the box.

Thanks
Robert

If you are not going to use the right column at all, best to set it to OFF in ADMIN>>>LAYOUT SETTING>>>Rightt Column Global Settings.

If you want a "wider" centre column (now your main column) then increase your #mainWrapper settings in the stylesheet.

Thanks, that did the trick.
It messed up the banner in the header but I know how to fix that. :D
(Unless there is a separate tag for center column of the body only??)
