Just a warning, I had some brand new kit lens that I purchased with several Olympus OMD EM-5's and EM-10's a while ago that I thought was a good deal at the time, only costing me $50 for each. So I decided to trade it in to Amazon who offered compensation that would allow me to make $10 per item or so. I thought sweet! Time to get these items out of my closet since they are just collecting dust. Amazon trade-in has a short form you fill out about the condition. I chose like-new because they were! They were brand new, and unused. Then amazon has an option you can check where upon arrival to the warehouse and inspection, I can choose to accept their condition report and value accordingly (if they disagree with my condition), or I can have the item returned to me. I chose 'accept condition value' since I knew they were brand new items and so I would have zero discrepancy between my reported condition and their inspected condition. Well they received my trade-in a week ago, and this morning I received the cash amount much less than what I should have received. It turns out they downgraded all 6 of my lenses from like-new (when really they were brand new) to 'good'. On ALL of the lenses they wrote the reason for the condition downgrade as: " Glass has slight marks that do not affect picture quality " This is obviously a complete lie. I had no reason to suspect amazon was going to cheat their customers so I did not do my research on the amazon trade-in program. However, after the fact, I googled and found out many many many similar cases. I contacted them and their summary was basically, 'well you should have selected to have the items returned - deal with it'. Just a warning guys, don't lose your hard earned cash.
