I know this post is a little bit late but this is a common newbie mistake. The company listed above is an aggregator that compiles information from storage facility's websites, newspapers and auctioneer's websites. The sell you the information that you can get for free with minimal effort.
I can't speak for every area, but in Dallas/Fort Worth & Houston, they miss 80% of the auctions. Why do they miss so many? Because it is a lot of work to actually call thousands of storage facilities on a regular basis. Why would they want to pay an employee to to make all of these phone calls when they can just visit a few websites, skim some auctions off the top and hope that nobody notices?

You know there is a problem when you visit their website and the first question in their FAQ is " Q: How often do you update your data? I am finding auctions not on your list!"
The truth is, they don't contact every facility in the country like they claim to. They visit other peoples websites and re-appropriate data that is convenient for them to find. You will never see auctions listed on their website that were published in smaller community newspapers because these auctions take longer to find.
If only you guys who use their service knew how many auctions you were missing, it would make you sick to your stomach.
