Website Updates Not Seen By Visitors

I apologize if this topic is in the wrong place. I could not find a section for website publishing problems.
I have the website www.clatterbrat.com and am troubled that after removing the Order page from the navigation links on the site, which I do this time of year to prevent orders until after New Years, visitors are still placing orders. It is as though they are not finding my updated site but an older copy that still has the order page. Can someone help me prevent this so that I can stop people from ordering my products until I am ready to accept orders?
