Adorama is offering a white box version of the Canon EF 55-200 f4.5-5.6 II lens for $150 and with free shipping. "White box" products are different from "Grey" and "Refurbished". We did not find an exact definition of "white box" on the product page, so if you are not sure what this means, please contact Adorama customer service. It comes with front and rear lens caps and a one-year Adorama warranty.
White boxes appear to be lenses that are separated (split) from a kit and sold separately, and put in a white box, instead of a fancy colorful manufacturer box. We do not know who makes the split, the manufacturer/distributor or the seller. Here are a couple of forum threads discussing them:
