Low Budget E-commerce site

Like I mentioned in my previous post, I use nopCommerce open source shopping cart. I host it at home and use dyndns for dynamic dns service which basically maps your host name to your home IP address if your ISP uses DHCP, which most, like Qwest or Comcast do. Usually, you would have to upgrade to a business account to get a static IP. Lastly, I use montastic for free site monitoring.
You'll most likely end up paying for the dyndns servcie, unless someone else out there knows of a better/cheaper way. Everything else...FREE.
