$13.99 is 18% under its usual $16.99, within a hair of its 90-day low.
- This deal ends Dec 3.

Why it's Wait
The price went from $16.99 to $17.99 on Oct 17, so you'd pay about 6% more than for most of the record. The only deal on record was a coupon at $12.99 (24% off) from late April to mid May, and just one is a hint, not a pattern. The record is under a year old, so other seasonal sales may be missing, and nothing is announced. A cheap item with a coupon that deep can come back with little warning, so waiting looks better than paying today's bump.
Next sale, maybe: No telling when, around $13.
