Question 1

How do I set or change a target price?

Accepted Answer

Enter a positive decimal target when you create a tracker, then edit it later from that tracker whenever you need to. Nabnook does not assume or assign a currency, so compare prices in the same currency yourself.

Question 2

What does my saved price history show?

Accepted Answer

Each entry is a price observation you saved, with the time it was recorded. Nabnook does not store or verify where you saw a price. Gaps between observations remain unknown and are not filled automatically. The latest observation can be compared with the one saved before it; this is not a continuous retailer price record.

Question 3

How is a deal score calculated?

Accepted Answer

A deal score is a 0–100 estimate based only on this tracker’s saved target and valid saved observations. Up to half of the score reflects the latest price against the target: it gets full credit at or below the target, and otherwise uses the target-to-latest-price ratio. The other half ranks the latest price among earlier observations for this tracker: earlier prices above it earn full credit, equal prices earn half, and lower prices earn none. A score needs at least three valid observations spanning seven full days. It is not a retailer-wide comparison, a prediction of future prices, or a guarantee of savings. If there is not enough valid history, no score is shown; that does not mean the score is poor.

Question 4

When will Nabnook email me about a target?

Accepted Answer

Target-price emails are off by default. Turn them on for an individual tracker to opt in. After you manually save an observation at or below that tracker’s target, Nabnook attempts to email your account address. An above-target observation does not trigger an alert. Email delivery is not guaranteed, and alerts are not continuous monitoring.

Question 5

Which product sources does Nabnook support?

Accepted Answer

You can save a seller link and enter a price you personally observed; saving a link does not mean Nabnook monitors that seller. Automated Amazon checks are currently unavailable: the former Amazon PA-API has been deprecated, and a supported API, authorized owner credentials, and a trusted scheduler are not live. Nabnook does not currently monitor eBay or local listings.
