The two major differences between the products are pricing and the domain that is included with each product. Pricing for Listing Domains is on a per website basis where Listings Unlimited is based on a monthly subscription (http://www.listingsunlimited.com/pricing.htm). The other major difference from our Listing Domains product is that Listings Unlimited sites use sub domains versus top level domains. An example of a top level domain is www.555MainStreet.com where as an example of a sub domain is www.77main.isforsale.com . Top level domains and sign riders can be purchased as add on features for the Listings Unlimited product.
