>I'd be interested to learn more about what Best Buy did to rework their processes, but I doubt it will become public because operational improvements like this can be a real advantage over competitors.

It might be simpler than you think. I've noticed that Best Buy's product listings consistently offer more product information (weight, dimensions, model numbers, and especially UPC) than the counterparts at Amazon, Target, and Walmart. All searchable, too; Amazon has the data but a) as mentioned, doesn't always make it visible, and b) doesn't always make it searchable.
