With all due respect 10Wheels, it appears you missed the point of my post and it’s somewhat naïve to presume two units remain simply because such has been advertised (especially where global sales are involved). I can’t tell you how many times I’ve ordered something where the vendor stated they had a more than ample supply on hand, but later find out that the item was backordered from the moment I ordered it!

Two purchases of a single 680 or a single purchase of two 680’s would empty their claimed stock and there are many individuals attempting to purchase these popular Cygolite Expilion 680 and 800 units (or the company would otherwise go out of business). So it’s reasonable to conclude that Amazon currently doesn’t have any remaining in stock at this very moment, but advertising that there’s two remaining in stock brings in a lot of orders via the hopeful and once they have your money, they really don’t give a damn how long it takes for you to eventually receive a backordered item, as it’s not their fault that they can’t acquire the item if its delayed or withheld by the vendor for whatever reason.

Additionally, consider the lack of customer reviews for the Expilion 680 and 800. This alone suggests there’s an availability issue with these newer units, as people tend to rave or complain about their lighting purchases, but where are all of the customer reviews for these new units?

Lastly, my LBS is Bike Line, which is one of the Cygolite authorized distributors and they haven’t been able to acquire these new units, so something’s not as it should be, as they have my two Expilion 680's on backorder at this moment.
