I would've agreed with you on this until recently. Tried to get an extra piece for something but they no longer make that 'color'. Then had the same issue trying to buy another malm piece to match the rest of the bed room. No dice, no longer making that fake wood facing and replaced it with a slightly different one. Different enough to look out of place.
If I break something or need more bits, I can always go back years later and get a matching piece.
