The price of a domain determines, whose offer will be transmitted. The position in the processing list depends on the domain price concerning of all Pre-Registration. If you are the highest bidder for a domain with 200 Euros, a bidder for another domain name with 500 Euros would be up in front.
You can see in the customer area, what currently is the highest bid, in what position you are in the queue and you also might edit your bid. We expect high traffic and load at the end of the Pre-Registration period and recommend you to take this into account and place the bid early on.
