Just noticed that Dinotte has some of their lights on sale through their online shop:

They have sales on both their AA and LI series lights . . . just drill down on either the "AA Pro" or "LI Endurance" section and the sale items are listed on top.

At least for the LI series (I didn't check the AA stuff), most of the sales are head/taillight packages geared toward commuting, but $405 for an L600 headlight with an L140 taillight is about the same price as an L600 all by itself. That's pretty cool.

I'm embarrassed to admit how much money I just spent on lights.
