Of course it was a fake craigslist ad.

I got really excited when I saw this 70-200mm lens on the Houston craigslist on Saturday.  It was even more exciting since we were gonna be in Houston that day.  Finally got a response:

Thanks for being interested in buying my Canon EF L 70-200 F/2.8 IS Lens, I will start my email by telling you that I’m currently out of country so pick up isn’t an option . The item is as described , in perfect condition and will be delivered at your home address . Total price will be $850 and the transaction will be made only through eBay because they will handle with all that it has to be done ,the shipping , payment and passing the item in to your property as they have authorization to sign for the item in my behalf . Right now I’m in Italy, just arrived here 3 days ago . Before I left I found a buyer and I had everything arranged . I paid for the shipping and almost sent it to him . But yesterday the buyer that I had asked me to wait another 4 weeks because he suddenly had other priorities and he is out of money for the moment . I can’t wait this long as I’m in the Italy for 3 days now and i really need the money, I am in the moving process , changing the work place and everything … A major issue is that if you want to buy my item you really need to have the money ready for it .
This purchase protection guarantees that the item is exactly as I described ; basically , once delivered , you’ll have 10 working days to inspect it at your home and if you decide not to keep it you will get refunded in no time and they will charge me with the return costs . If the item meets your expectations and you want to keep it you will have to tell them to release me the payment details so I can get paid . If you are interested in this purchase please reply me with your full name and shipping address . After i pass this details to them you will receive an invoice and further instructions as how will you be able to get possession of the item .
Let me know your thoughts .

Warmest regards
