Notify Readers of Updated PAGE

I have a page on my blog that has weekly winners to giveaways.

Because it’s a PAGE and not a POST, can there not be an RSS feed for this page? Is there a way to email readers when this page has been updated?

I have the excerpt in my sidebar that shows recent winners, but was wondering if there was a way for readers to subscribe somehow without having to remember to come check my site.

Any ideas?
