Hi Devon,
Looking at your site, this is what I see...
When you click on the store locator in the menu, you are taken here http://www.jakesfireworks.com/locator/
From there, you can click on one of the state links or search. If you click on a link, you are taken here, for example:
http://www.jakesfireworks.com/locator/?state=AR
But, if you choose the state from the drop down, you are are taken here http://www.jakesfireworks.com/arkansas/ Am I right in thinking that the pages like this are being done just for SEO purposes? You also seem to have different location landing pages, depending on the route you take. Is this what you want to combine?
How do you rank for local results right now? Does each location have its own Goole Local page?
I would be very tempted to 301 one page to another or at least set a canonical tag pointing to your preferred page, but I certainly wouldn't leave it in its current state.
