Why stores cancel price errors
A price error is the store's mistake: a mistyped number, a discount applied twice, a bad figure from a supplier. The store can almost always cancel it, and often does.

An example from this week
On November 5, 2026, barato.si flagged a Targus USB-C dock (DOCK215USZ) at 59.99 USD on Amazon. CamelCamelCamel had its previous price at 287.99 USD, so that day's price was 21% of the reference. That is the kind of drop barato.si marks as a possible error, with a single reading behind it. It may be an error, a clearance or a misread figure, and the page says so.
Why they can cancel
The terms of sale of large US stores usually reserve the right to cancel orders placed at a wrong price. At several of them, the sale is not final when the confirmation email arrives, but when the order ships.
The "we received your order" email confirms exactly that: they received it. It does not promise to ship it at that price.
How to buy without getting burned
Pay with something that refunds fast if they cancel. A credit card usually releases the hold in days; a gift card balance can take longer.
Don't buy anything else counting on the error arriving. If it arrives, great.
Don't order twenty. Large orders at an error price are the first to be cancelled.
Buy a price error fast and celebrate it slowly.
