Say you buy a camera with 1 year warranty. The serial number doesn’t hold the date of your actual purchase. That is why, you are asked to send back the Warranty card, which most of us never do.
It is unfair to say that manufacturer do not wish to get the actual purchase date. If they do, they won’t include the Postal-paid thingy on the card. So, where goes wrong?
No one say you must follow the long-winded template of warranty-card design. Make the change!
