At its record low, never cheaper in a year

The current price of $19.99 matches the lowest point recorded over the past 365 days, exactly at the floor seen during that period. Compared to the usual reference price of $39.99, the gap reaches 50%, and the yearly high of $42.99 shows how much more the product can cost at other times.

The most telling benchmark, though, is the price realistically achievable under normal conditions, $29.06. That level was only reached twice and held for just 28 days total over the year, making the current price notably better than what buyers can typically expect. The 90-day trend is also slightly downward (-2.8%), and the price has been very stable, changing on average every 33 days.

Across the 20 commercial events observed (Prime Day, Black Friday, etc.), none offered a genuine discount, suggesting that waiting for one probably won't help. Since the price already sits at its historical low, there's no lower threshold to wait for: right now appears to be the best opportunity seen so far.
