We know someone who ordered a book online but was confused when a much different volume was delivered. Not the right title or shape at all, much less the anticipated title. The seller was quite perplexed, too.
So the order was placed again, with another supplier, only to produce the same mistake in delivery. The very same wrong title, in fact.
Only after checking the ISBN (International Standard Book Number) did anyone notice the two titles – the one ordered and the one delivered – had identical numbers. I thought this was supposed to be a fool-proof system. How often does this happen?
As for the warehouse, I’m left wondering: Doesn’t anybody read the title anymore? A double-check for accuracy. And that was well before the Christmas rush. For the sellers, this was a costly error.
