Sometimes the same product (be it a camera, TV, dishwasher etc) can have different numbers for different stores or web sites.

So John Lewis for example might ask a company to make a product just for their stores with a "different" number (it may be only one digit different).

This stops people being able to do easy price comparisons by searching the web.

Not saying that is the case in this instance.
