We use an item’s 12-month price history when we assess a deal. We’ll happily examine an item’s entire price history to establish year-over-year trends, but an item at its lowest price in a rolling 12-month window is almost certainly a deal.
And despite our analytical approach, we aren’t totally rigid in our deal assessments: We recognize that if an item had a great price at $91, it still has a very good price at $93, and our readers are likely to be happy to see that good (if not great) deal. Still, we post fewer of this type of deal than other deal sites do. Why? Because our robust price tracking and extensive research allow us to post only the deals that have truly great pricing.
