This particular issue is tricky for Newegg. The items in question are Intel Core i7 920 CPU's, which, we all know, come in a sealed box and may be hard to inspect without opening the box. Newegg would not sell a new item with the box opened, so again, really really tough for Newegg to have know there were fake CPU/heatsinks in said boxes. The perpetrators in this situation probably made sure that the weight of the counterfeit boxes were the same as the legitimate i7 920 boxes. This is not really brain science for the evil-doers as it is an easy way to exploit a good company such as Newegg. So, regardless, Newegg should clearly not get the blame, nor should the shipping company, this is pretty cut & dry.
As for Newegg's company policies and attention to detail & customers, well, that is where they are at an advantage, they will get backed by anyone out there in regards to this matter simply because of the way they operate. They offer numerous varieties of various products all while maintaining a loyal customer base. In these trying times, even a loyal customer base can only get you so far, yet, Newegg prevails.
Show me a company with the same ethics/policies/foundation as Newegg and i'll show you a successwful company and the customer base to back them up. The people who are responsible for this mess are the only ones to blame here.
Now, if only there was a company out there that sold Quality pre-built PC's that had prices and customer service comparable to Newegg. something with custom configuration options as well as pre-built. You know, for those people who prefer not to put up with the hassle of building... Like Dell using Cyberpower PC's component selection @ a lower price... Hmmm..., who wants in?
