Listing price
The amount shown on the item page at observation time.
A saved price is an observation with a date, not a fact about tomorrow.
The worksheet keeps amount, currency, source wording, and observation date together, so a later reader can tell a changed price from a misremembered one.
Evidence path
The path copies first, contextualizes second, and schedules the recheck third, so no saved number pretends to be permanent.
Price fields
A retraceable price records where the number appeared and what it excluded; anything else is a floating number waiting to mislead.
Price states
The amount shown on the item page at observation time.
A different amount caused by the exact size or color option in the row.
A saved price whose recheck date has passed; it stays for history, not decisions.
Two observations disagree; both stay dated in the row until a fresh check resolves them.
Quick FAQ
Save the original first; a converted amount is a note with its own date and rate source.
Record the cart view as a separate observation with its own date and boundary.
Once its recheck date passes or the platform flags the listing as changed.
Reusable output
A second reader should be able to retrace the observation, compare the saved fields, and see exactly where the record stops claiming anything.
Write the number exactly as shown and name the currency; converted values get their own line.
Note whether the price came from the listing, a cart view, or a seller message.
Record the visible boundary: whether shipping, fees, or options were outside the shown number.
Stop rules
A named gap keeps the row honest; a filled-looking gap borrows confidence the source never provided.
Keep the record small, dated, and tied to one exact source.
