I can't access it either from mobile network so I'm sure its a router issue even though the ports are forwarded to the correct IP. I'm working on putting it in a more permanent location on friends server.
The site has been updated to allow you to submit the price you found if the price calculated is "good" or "great", which currently is < $0.26 / oz of chlorine. Once a price is submitted, it will show in a section called "Current Sales by Store Name" after you reload the page. There is also a search by Zip Code but it isn't all that useful without knowing every zip code for each store of the same company, so I may remove that feature soon.
If anyone submits a price, be sure not to use a forum nickname when submitting a price if they don't want it listed along with the zip code they enter for the price. There is a warning about this on the page.
