However, Pool uses what some have called a “two-phase” auction system. This means that once you win your original backorder, Pool will then move you into the auction phase where you compete with other bidders for the domain. Pool doesn’t reveal how many bidders there are or what they’re bidding, so you have to offer the highest price you’re willing to if you want to get that dream domain.

Your course of action really depends on how much work and effort you can put into the expired domain. If you're barely able to maintain and optimize your current site, you probably want to just 301 redirect the old site (note: see my amended comment above about the link value not likely to be passed). If, however, you're more creative and have some time on your hands, you can try your hand at crafting a microsite. If you really know your stuff and are experienced at making money off various websites, you'd probably do well with the third option.
If you bid at NameJet *after* the domain name moves to Pending Delete status, then it’s too late for NameJet to take advantage of their relationship with eNom and take control of the name. So then eNom thinks, “no interest from NameJet users; we’ll just drop it” and it goes through the regular deletion process — where the fastest fingers can register it. In some cases, investors don’t want to pay the $59 or $69 fee at NameJet and if there are no bids they can likely get it for $18.99 at Pheenix or using other dropcatching services.
This wonderful piece of information about buying expired domains is simply mind-blowing and I did not know about that before. It is easy for every one to understand about the topic with the pictorial representation. I feel sad that you lost around $400 due to Fake PR, but this article will surely help others save them from any sort of inconvenience.

Thousands of domain names expire every day. The reasons are different. Some owners forgot to renew the domains, some just don't want them anymore or they moved on to other projects. For most people these so called Expired Domains don't have any value. They just see a bunch of Domain Names someone else deleted and move on, but for the people who know about SEO or the value of good Backlinks, Expired Domain Names are money just waiting to get picked up from the street. The only problem is to separate the good ones from the bad ones. That is where comes into play.
