question Why do domains on Sedo sell for so much higher?

[Marketseller747]

I've noticed a trend, specifically with 3L .co's. For example the average selling price is $300 across the board. However, Sedo's average price for these domains is $2,500.

I've also noticed that almost all names on Sedo sell for $1,000+. Is there a reason for this? Does Sedo reach end users directly? Or is it that the auctions gain more exposure?
