Put the drill down. It's had 3 sales since Jun 2022 that would beat today's price, usually 15% off ($3.99). From spots like today's, one came within six weeks about 5 times in 10.
- It went 36% off ($3.00) in late October two years ago. One sale is a hint, not a pattern.
How sure is that?
The odds come from everything since June 2022, with the past year counting double: 28 days like today and what followed. That's a short record, and Harbor Freight changes its plans, so take it as a lean, not a promise.
