What the pattern tells you
Today’s $499 is $165.94 below the 15-month average and $500.99 below the original launch price. It also matches the lowest price this exact ASIN has ever recorded, first hit in April and holding again now. That’s a different situation than catching a temporary dip: this is the floor, not a step toward it. Waiting for a deeper cut means betting against 15 months of data that has never shown this listing below $499.
The Walmart and third-party wrinkle
Walmart is currently matching this exact price at $499. Third-party used listings on Amazon go lower, averaging $407.28 over the tracked period with a low of $353.34 recorded this month, but that market carries condition risk a new unit with full warranty coverage doesn’t. For a new unit, $499 is the number backed by the strongest track record here: the documented floor of the last 15 months.
The catch with any price-history read
Fifteen months of tracking is a real record, not a guess, but a price floor can still move lower over time as a product ages or a successor model launches. Nothing in this record rules out a future price below $499, it just confirms nothing has gone there yet. If you’re shopping now, $499 is the best price this exact listing has ever offered, not a reason to wait on a maybe.
Before you buy
The data makes the case directly: $499 ties the all-time low and sits $166 under the 15-month average. That combination is rare enough to act on rather than watch.
