Make public pages unviewable

Here is what I am trying to do. I am running a sale with 3 different prices for the same product. So I have set up 3 different sales pages on my site. I tried setting them private and then realized that no one could see them. SO i set them public.

The problem I am running into is that now they are all displayed at the top of every page with a link to them. That won’t work. I don’t want them displayed and I want them to be available when I send someone the link.

I found this site:

http://realiventblog.com/2007/06/15/hiding-pages-with-wordpress-part-2-errors-omissions-and-solutions/

Will this work with version 2.6? Or is there an easier way to accomplish this?

TO sum it up I want a page I create available for someone to click a link and get the p ge and not have the page show up on the main page like most pages do.

Thanks,
Adam
