> Creating SKUs to avoid price matching is still just having one product coming out of the factory. It's just extra space in a database somewhere, so it costs nothing.

They also have to label the products. But yes, it costs almost nothing to the manufacturer, but the effect on the consumer is large.

Also, for flatscreen monitors, I think differences go further than model numbers. It’s things like number of inputs, number of outputs, max power delivery, color of the frame, etc.
