So, in short.
We no longer have the ability that we had pre legislation?
Correct.
But as the guy who mentioned monitors we view backlight bleed or poor finishes a fault and will refund in full even if the law stipulates we could legally give a partial refund as with monitors we class it as a fault.
But people who think they can buy a VGA card, clock it to hell and back, obtain some scores, then return to us under DSR, then yes you are correct a re-stocking fee will apply. Don't laugh we've had a few customers do this under DSR.
Your buying a new VGA card based on reviews, its specification and from the many photos and potential videos online. You know you want and need it, so unless it was faulty you'd have no need to return it.
