Azra, after years of buying from Newegg.com (at least 5 years), I can tell you that I never had any problem with their delivery: Every item I purchased from them, showed up at my door promptly and in good working condition.
However, a recent incident with Newegg's review system, suggests to me that they are not always telling everything about certain products.
For example, when I discovered that Western Digital WD7500AACS hard drive has no warranty terms on Newegg's web site, I wrote a quick review to share this with other customers, just as other customers' reviews help me make purchasing decisions.
Newegg's response was... to reject it, never publish it - with all sorts of excuses. You can read all about it here:

I also documented my experience on this resellerratings.com web site:
Newegg.com Reviews, Ratings and Prices at ResellerRatings
Again, I have yet to experience any problem with Newegg's delivery system (and justified returns). But my advice to you is to take into account that not every review, that has ever been written in good faith by loyal Newegg customers, is published.
BTW, I am about to purchase a $4,000 color laser printer for my business, and this is the first time that I am consciously
not going to buy it from Newegg.
HTH,
