At an all-time low, sales events bring no discount

The current price of $17.99 matches the lowest point ever recorded over the past 365 days, a level never reached before. It reflects a 78% drop from the yearly typical price of $79.99, with a strong 90-day trend already pointing downward (-37.6%).

The price floor that was actually reachable in practice sat closer to $19.99, a level hit only twice and held for 16 days total. The price rarely moves at all, changing roughly every 40 days on average, so shifts are infrequent but notable when they happen. During the two commercial events observed (Black Friday, Prime Day type events), no real discount was applied, making it unlikely that waiting for the next one would help.

At $17.99, the price is already sitting at its historical floor. Given how stable it normally is and the lack of any real deal during past sales events, there's little reason to expect it to go lower soon, so buying now looks like the more sensible move.
