Why it's Fair
The coupon runs through 2026-11-08 and matches the May 2026 coupon at $14.99. Earlier coupons and sales hit $9.92 to $12.99, including a Black Friday-week coupon at $12.99 in 2024 and a $11.99 sale in late 2023, so today is not its best. Those deeper deals all came before the price rose to $19.99 in 2026, and the two 2026 dips both stopped at $14.99. The odds of a clearly better sale within six weeks are low (4%), and nothing is announced, so it is a fair price, not a rush.
Next sale, maybe: Late November, around $13. A long shot.
