I've seen a bunch of these weird postings show up all over Amazon lately. In fact, tonight I saw this lens in "Very Good" condition listed for $800, so I bought it immediately. Soon afterwards, I got a notice via Amazon that my order had been cancelled due to "Technical Difficulties."
Now, the same seller has the lens listed at $10! http://www.amazon.com/gp/offer-listing/B000EW9Y4M/ref=dp_olp_refurbished?ie=UTF8&condition=refurbished
I'm not sure how long it will stay up because I'm calling shenanigans on the whole thing, and I'm sure Amazon will catch up if it's truly fishy. I've always had good experiences with Amazon when their sellers have been dodgy because they manage all the money flow and immediately have refunded my payments from shifty sellers.
Has anyone had experiences with these sorts of things?
Thanks in advance!
