Benton Harbor, MI shelf$16.99same shelf price as online
$16.99 is 13% over its usual $14.99 and past sales hit $11.99, so waiting looks better.
$16.99 is 13% over its usual $14.99, up since Nov 2. Nothing in its record says when, or if, it comes back down.
- It went 20% off (around $14) in mid November two years ago. One sale is a hint, not a pattern.
Why it's Wait
The price went up on Oct 16 from $14.99, which was its regular for most of the past two years. The record shows six sales or coupons at $11.99 to $12.99, and the last one ended Oct 9, 2025, so nothing has come in over a year. Odds are low on the formula, but it has had coupon dips at least twice a year before, and a cheap item like this drops by a big percent when they hit. Nothing is announced, which doesn't rule one out.
Next sale, maybe: No telling when, around $13.
