Go to AmazonWe are not ready to call this price.
We check at least every 20 hours and hold a day-by-day record of what this cost: 5 days of it so far. Calling a price high or low needs 7 of those days and at least one change, because a range needs two prices: this one has not moved since we started watching. If it is still $349.99 on November 5, 2026, this box will say so: a price that has held for 10 days is an answer too.
