Some days ago I've submitted a question like How can I be convinced the purchased items are new not simply the stuff. I hope I will get good answers.
I think that it depends on quality of things. The prize must be correct. On this way only we can be proud to sell a good product or make a good service.
How to sell something, expensive or cheap, depends not only on our decision. Our products would maybe not accepted on the list of TripleClicks, if they are too expensive.
