Just another anecdote...sold a 70321 General Magmar's Siege Machine of Doom about a month ago via FBA. A couple weeks later got a notification of return, and debit to my account. Last week got notification that the returned item was in "unsellable" condition, with the reminder that this inventory must be removed from Amazon immediately (recalled by me, or disposed of). Like most small time sellers, I am shocked to find that if a buyer orders a Lego set from me via FBA, opens it, loses half the pieces, then calls Amazon and says, "I just don't want this anymore... changed my mind", that they will get a full refund as soon as they drop it in the mail. And even once received back at Amazon, after inspection they confirm that it is, in fact, "unsellable", the customer still gets to keep the full refund, and the loss comes out of my pocket. Ah well... you wanna play on the big stage... that's the way it goes... ok... fair enough.
So anyway, I learn it will cost me $.50 to recall this item (in spite of the fact that Amazon is offering FREE recalls of all inventory right now... guess it does not apply to unsellable inventory). So I recall it. It arrived today and guess what - it is an absolutely perfect sealed box 70321. Nothing wrong with it. Curiously tho, it is NOT "one of mine". It does not have my SKU barcode on it, but in fact some other kind of barcode from some other seller. My guess is, they ordered from me FBA + Amazon Prime to get it in time for little Timmy's birthday. And then ordered another from an FBM seller... maybe for $10 less? When the second arrived, they returned it as "mine" and pocketed the difference? Still can't understand how Amz decided that it was "unsellable" tho. Maybe not having my barcode on it makes it unsellable? I'd like to raise a little fuss about it, but I guess I should just count my blessings, ...and send it back in.
