Wishpicks captures a wish's price once, when you add it. After that the price only updates on its own while the wish is being tracked, and tracking pauses for a handful of reasons.
Why a price stops updating
The wish can't be tracked at all. A wish with no link, no captured price, or from a store that doesn't allow tracking (Amazon is one) never gets checked again. These show as Unavailable.
The store needs Wishpicks Plus. Free price tracking works on partner stores only; any other store needs Plus for ongoing updates. Without it the wish sits with tracking Off.
Price drop alerts are switched off. On a partner store, free tracking only runs while your account's Price drop alerts setting is on, and it's off by default.
You've hit the Plus tracking limit. Plus tracks up to 50 items at a time, and a new wish won't start tracking until you free up a slot.
The price is in a different currency. Even on a tracked wish, Wishpicks only writes a new price when the store's currency matches the one already saved on the wish. That stops a price from a different regional version of the page overwriting yours in the wrong currency.
Good to know
Stock and link checks still run on a tracked wish even when the currency doesn't match. Only the price itself waits for a matching currency.
The first price you saw is real. Capturing a price when you add a wish works on any store Wishpicks can pull details from, with no Plus needed. Plus is about the ongoing updates, price history, and custom alerts.
Price-drop alerts come by email, batched together, and never instantly or in-app. Plus gets them more often than the free tier. See "How do price-drop alerts work, and how often are prices checked?" in the Wishpicks Plus collection.
There are no back-in-stock alerts; see "Will Wishpicks tell me when a sold-out item is back in stock?"
