There could be another mechanism going on. When I worked retail in cameras, we had incentives to sell more of one brand over others. So if we sold 20 cameras for that manufacturer they would charge one price. But if we sold 21 cameras that month for the manufacturer they would give a hefty discount for all the items that were purchased.
If we had sold 19 or 20 cameras for the month and needed one or two more to get the promotional discount, it was more profitable to sell the remaining that were needed at cost or even for $0.01 to net that extra profit.
Festool might have a similar discount plan. For example (with my invented numbers):
All dealers get 50% off list price.
Dealers who sold $50,000.00 for the month get 60% off list price.
So discounting one item might put them over the threshold to the larger discount and greater profit on all the items sold that month.
I am not saying that is what is going on, but it is a fairly common practice in retail. Automobile manufacturers do that regularly. That is why the terrific deal you were offered on Friday, the last day of the month, disappears on Saturday, the first day of the next month.
Of course if they made the quota earlier in the month they will not offer those great deals.
