BuyDig via eBay seems to be the only store that gets the concept of a “Cyber Monday Sale”: they have the Sigma Contemporary 150-600mm f/5-6.3 DG OS HSM for only $700.00. This is the lowest price we’ve seen yet for this fantastic lens.
Canon, Nikon, and Sigma mounts are available. The listing clearly states this is a brand new lens with a USA warranty. As BuyDig are an authorized Sigma dealer, this would be a 4-year Sigma USA warranty. This is an epic price, and will sell fast!
UPDATE: As of 8:30 AM, the listing is changed to “Open Box – Closeout”. This isn’t the first time BuyDig has modified an eBay listing after the fact (likely to hide the fact they’re selling below MAP.) Rest assured that the description at the time you purchased is the agreed condition as per eBay rules. Also, BuyDig has a history of listing things as “open box” or “refurbished”, and then shipping brand new items, so this is probably still new anyway. See here, here, here, and here.
UPDATE: As of 8:48 AM, Canon mount is out-of-stock. Congrats if you got in on the deal.
UPDATE: As of 11 AM, looks like Canon mount is back in stock!
