This means that the item is at an Amazon Fulfillment Center (probably in KY) and will be shipped from Amazon, not a 3rd party. It also means that there are no charges for second day delivery if you do/had signed up for Amazon's "all you can eat" Prime shipping rate ($79 annually for everything you buy that qualifies for Prime).
I buy 95% of my electronics and many other items from Amazon. I recently purchased my entire home theater system from Amazon. That included LCD TV, A/V receiver, DVD, Tivo HD, furniture cabinet for components, cables, power conditioner, etc. I researched on Amazon, CNET, and forums (avsforum.com). I installed and integrated all the components myself. My savings vs buying from Circuit City or Best Buy, and using either of their install services, was close to $3000.
Amazon also offers a 30 day money back return policy on items they ship directly.
Should you buy from Amazon? Absolutely. I have not shopped the price of your item, but you can try B&H Photo (reputable) and JR (jr.com) if you want to be certain.
Thanks! Going to get it now. I really appreciate your advice, as well as that of the other experienced Amazonians (LOL) on this thread. Yeah, I have Prime too - love it.
