What was the lowest Amazon price in the 90 days before this check?

$5.60. At our check on Oct 18, 2026, the price was $5.60.

What does the “typical” price on this page mean?

It is the time-weighted average of Amazon’s own price over the 90 days before our check: $13.82. The median was $9.89. A short price spike pulls the average up, so the median is the better guide for this item.

How often does the price change?

Amazon changed it 5 times in the 90 days before our check, about 1.7 times a month.

Is this still the price today?

Not necessarily. We recorded $5.60 on Oct 18, 2026. Amazon sets the current price, which the listing and checkout show.

What the 90-day history shows

At our check on Oct 18, 2026, Amazon’s own price was $5.60. In the 90 days before that, it ranged from $5.60 to $23.33.
The time-weighted average (the “typical” price) was $13.82; the median, the price it sat at or below half the time, was $9.89.
It was at or below $5.60 for less than a day of the 90 days Amazon listed a price.
It had been at or below this price since Oct 17, 2026. Before that, the last time it was this low was Oct 17, 2026.
Amazon changed the price 5 times in that window, about 1.7 times a month.

Check the “typical” price. A short price spike inflates the average. The price peaked at $23.33 and sat at double the median or more for about 31 days, which lifts the 90-day average to $13.82 even though the item usually sold near $9.89. Against the median, the checked price is 43% lower, not the 60% the average suggests.

Rule-based answer

Was it a good time to buy?

Yes. At our check this was one of the best prices in the last 90 days.

It matched or beat every Amazon price in the 90 days before the check.
It was at or below this price for only less than a day of 90.
It was 43% below its median price of $9.89.
The “typical” price is inflated by a short spike (see the history notes), so the headline discount overstates the saving.

This check has expired, so treat it as history, not today’s price.

Before checkout

What should you check now?

Confirm the size, color, seller, shipping and current total on Amazon before buying.

For Tools & Home Improvement, also confirm on the listing:

Tool-only vs. kit: whether batteries and a charger are included in this price.
Battery platform and voltage, if you already own tools from this brand.
Who honors the warranty, and the return window for the seller shown at checkout.

Amazon’s checkout total—not this page—is the current source of truth.
