Reading a 90-Day Price Signal Without Fooling Yourself
Use price history, shipping, inventory freshness and seller confidence together instead of reacting to one low number.
Start with delivered price
A lower item price is not necessarily a better deal when mandatory shipping changes the total. Compare delivered cost when that information is available.
Check the time window
A 90-day low describes the tracked window, not an all-time low. Seasonal gear and discontinued models can behave differently.
Confirm stock freshness
An old low price attached to an out-of-stock offer is not an available deal. TackleSonar separates stock status and price snapshots so the chart is not treated as an order button.
Use alerts as thresholds
Set a target based on what you would actually pay. An alert should reduce repeated checking, not create urgency around every small movement.
