Kogan lists all his TV's on Ebay for 1C with no reserve.
If it doesn't reach a profitable amount he places a bid himself and "Buys" his own TV.
It takes 2 seconds to create new Ebay accounts and email addresses. He probably has someone employed doing nothing else.
Think about it - why else would he sell everything via Ebay instead of focusing on his own E-commerce site. Plus whenever you buy out your own item you can post a "Positive Rating".
All of a sudden his 99.7% feedback rating makes alot more sense.
A little bit of humble pie would go a long way Kogan - you're not doing yourself any favours.
