So, should you buy?
The current price of $54.59 matches the lowest point observed over the past 365 days, a level reached twice and held for 96 days in total. The 365-day reference price stands at $470.46, placing the current price well below that calculated benchmark.
The price has been very stable lately, with zero movement over the past 90 days and changes occurring on average only every 52 days. During commercial events, a genuine discount showed up just 7 times out of 28, and in an equal number of cases the price had first been inflated ahead of the event, a pattern worth keeping in mind when judging future promotions.
Since the current price already matches the lowest attainable level and volatility is low, there's no indication that waiting longer would bring the price down further. Prime Big Deals events have historically delivered the best discounts (around 9.5% across 3 editions), a benchmark worth watching if choosing to wait anyway.
The verdict
Buy now.
Worth it
The current price is among the lowest in its history, and well below its usual level.
