I put up a little banner, clicked on it and placed an order with Staples in the wee hours of the 26th (last day for free shipping), then realized I'd ordered a mouse but needed mousepads so I called customer service to add them. They said to just place another order, so I clicked the banner again and submitted a 2nd order. Both were to be delivered on the 28th (tomorrow).

Both orders were just delivered (the 27th), and both tracked at CJ.

There were 2 sales recorded (and paid), 3 clicks and 1 impression, so apparently sales and clicks are counted, but only 1 impression.
