What the 90-day history shows

  • At our check on Oct 3, 2026, Amazon’s own price was $14.16. In the 90 days before that, it ranged from $9.39 to $70.99.
  • The time-weighted average (the “typical” price) was $28.50; the median, the price it sat at or below half the time, was $27.99.
  • It was at or below $14.16 for 15 days of the 90 days Amazon listed a price.
  • It had been at or below this price since Oct 1, 2026. Before that, the last time it was this low was Sep 27, 2026.
  • Amazon changed the price 67 times in that window, about 22.3 times a month.

Rule-based answer

Was it a good time to buy?

Probably. It was well under its usual price, though it has been cheaper.

  • It has been cheaper: the 90-day low was $9.39.
  • It was 49% below its median price of $27.99.
  • The price moves often (about 22.3 changes a month), so it may change again soon in either direction.

Evidence sheet

What cleared the gate?

Before checkout

What should you check now?

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

For Health & Household, also confirm on the listing:

  • Count, size, or dose per pack, and the price per unit (our unit-price calculator helps).
  • Expiration dating on arrival for anything consumable; check the seller and return terms.
  • That the price is the one-time price, not a Subscribe & Save or coupon price.

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