I remember years ago I was looking to buy a large Indian rug. I was watching one but as the end drew near I couldn't access the page. It ended at something idiotic like £40 and I was raging. Then I realised that it had ended so low because no one else could bid either!
So
ebay's glitch cost someone hundreds of pounds. What is more the seller almost certainly didn't know that this had happened. If you think about it this must happen regularly, all computer systems have glitches and downtimes. Makes you think. Yet another reason not to use eBay.
