The seller's shop search glitch occurred last month too.

 

It caught me and eventually I gave up and bought elsewhere, and returned to eBay days later when I was able to see it had stopped. So eBay certainly lost sales on behalf of itself and its sellers. How many other buyers are affected = sales lost?

 

But there are worse glitches as candidates for eBay Glitch of the Month. eBay could own them (own up to them) by monetising it all, e.g. sell a Glitch Calendar to hang proudly on your wall. Which Glitch would take the centrefold? 🙂
