OEM != returned, refurbished, or anything else that would cause it to be of lower quality than a retail product. OEM stands for Original Equipment Manufacturer... basically what it means is it comes bare in a white or brown box with no documentation or software rather than a pretty colorful box with a manual in English, French, German, Chinese, Japanese, and Russian with driver discs and trial software and game demo's. OEM products aren't intended to be put on store shelves... they're intended to be purchased in bulk for system builders who don't care about flashing packaging or accessories... hence the reduced price compared to the retail packaging.
