I do not use eBay often, but occasionally troll there for equipment "deals", so this really struck me as odd:
"EF 400mm 2.8L IS USM NEW IN BOX" with a starting price of $4.13. In the body of the add the seller claims that the BUYITNOW price is $1,300.00 but I need to contact him at his gmail account. curiosity prompted me to send an e-mail. The response was even more bizarre: "The buy it now price of this item is US $1,299.00, free shipping.We offer 30 days to return it if by any reason you are not satisfied with it.In order to start this transaction we need your ebay username,full name and shipping address...You will get an ebay invoice with the new buy it now price...The item will be shipped only to the payment address."
I may not be the brightest bulb on the tree, but this looks like a pretty amatuer scam to me.
Reality check, please.
