Start with the job the product must do, then narrow the field using documented facts.
Model, seller, included items, delivery, warranty and returns can change after publication.
We distinguish current catalog evidence from editorial judgment and leave unsupported claims out.
Observation is not price history
MKT Store begins tracking from the first verified snapshot stored by this system. It does not reconstruct earlier prices or label an offer an all-time low. A movement appears only after the same ASIN has two different genuine price observations.
What a movement means
A lower observed price means the latest recorded amount is below the first amount in our local record. It does not guarantee that the price will remain available, that no lower price existed before tracking, or that another seller has the same terms.
How to use this desk
Treat a change as a prompt to recheck the exact Amazon offer. Confirm seller, stock, delivery, variant and checkout total. The time stamp establishes when MKT Store observed the data; Amazon remains the final source at purchase time.
Build the baseline
Each verified snapshot records ASIN, current price, reference price and observation time.
Report material changes
A movement is shown only when two genuine observations exist for the same product.
Keep the timestamp visible
Readers can distinguish a current observation from a historical guarantee.
Changes recorded since tracking began
These movements compare genuine MKT Store observations for the same ASIN. They are not all-time price claims.
