Interesting story - but you have to wonder why didn't they use shopping carts as they would have carried far more books in a much shorter time span.
As you may know, shopping carts stop working when you leave the store parking lot (unless of course they are tampered with and I am sure you were not suggesting tampering with shopping carts. I am sure that is right up there with removing tags off mattresses in criminal circles).
