Here's an interesting exercise for a rainy day when there's nothing on the telly. Point your browser at the Wal-Mart web site and go to the company's property section. Here you will find details on every building that is now surplus to Wal-Mart's requirements in the US. There's pages and pages of the stuff. We haven't done the sums, but one academic claims to have added all the space together and he insists that Wal-Mart has 28 million sq ft up for grabs! And this at a time when it is going through its biggest ever expansion. Makes you think, doesn't it? {{COUNTERPOINT }}
