Here's another way for buyers to con sellers in eBay;

Let's say I am selling a purple widget, and I set it up as a 99p auction, but with a "buy it now" of £20.

So, a buyer comes along and makes a 99p bid.  The option to "buy it now" disappears.  That buyer then contacts the seller to offer to buy it now for £10.

How many sellers have fallen for that con trick?
