How do I take a picture of the serial number?

To qualify for this cashback promotion, you must cut the serial number together with the barcode out of the box. It is not enough to just take a picture of the serial number while it is still attached, or to peel the sticker with the serial number off the box. You need to cut it out, so there is a hole in your box. Then take a picture of the cut out serial number and barcode.
