Sparefoot / SUAL Alliance

I just noticed that Storage Unit Auction List has partnered up with Sparefoot, one of the largest storage aggregators. Looks like SUAL is providing the content. They display one auction for free and if you want more, you have to sign up for the service. Sparefoot probably gets a kickback if you join. Sparefoot is a great site, but I'm just not so sure that their audience (people looking for storage) will be interested in storage auctions. But, I don't see how it could hurt either site.
