In past I did similar kind of research and you can read it by clicking following link.'
Not sure he is collector or dealer or other.!!! who bought from some famous seller such as "alphaomegaphilately" , "ashokmehta1955", "gorfa" , "london-stamps", "mareval2" , "posthost" and others.!!
Following are details (click to see enlarged copy to read it) if you want to see what else this buyer is buying and from whom and for what price.!!
You can do this for any buyer and find out before you make your conclusion about fair price for any of your collection.!!
Now as per following quotes of some famous people, it's upto you to THINK, UNDERSTAND and DO BETTER.!!
“I cannot teach anybody anything. I can only make them think” ― Socrates
“Any fool can know. The point is to understand.” ― Albert Einstein
“When you know better you do better.” ― Maya Angelou
So what do you think about this auction and buyer's activity.!! Do you think this is correct price or any cheating is involved in this deal such as
1) Shill biddding (i.e. bidding with other id or friend helping to increase price)
2) Buyer not paying to seller
3) This is the right price of the item?
