Suspicious point #1.) The board was not in plastic wrap, but came in its little zipper bag. All burton boards come in a plastic wrap, and some have the addition zipper bag. It did have the sales tags in the channel, price tag, and booklet attached.
In my experience, boards usually come in either a plastic sleeve or plastic wrap depending on the brand. None of my Burton boards have ever come in plastic shrink wrap. I've ordered 10+ Burton boards over the last few years from various retailers, inlcuding Sport Chalet, Darkside, Whiskey Militia, Tru Snow (Sierra), and Active Ride Shop.
