Completed my second successful transaction with Greentoe. 70-200L 2.8 IS for $300 less than list at the big superstores in NY. I had never heard of the authorized US seller before, but the lens was delivered in three days. The transaction took a little over a week since my initial offer was $50 below acceptance. Greentoe staff emailed several times but I did not budge. My offer expired after 7 days, so I increased a second offer and the deal was made after two days with help of Greentoe. I think their staff makes a real human effort and earns every penny of whatever they make on the deal.
