WalletWhistle tracks product prices and notifies you when prices move. The aim is simple: transparent, timestamped price history so you can decide when to buy.
Data on this site currently comes from Awin-connected merchants, with each observed price stored as a dated snapshot.
WalletWhistle captures prices when products are first discovered and during ongoing refresh checks. Every captured price is stored with its own timestamp so changes can be audited over time.
Product pages show the latest known price plus historical points where available. Alerting is designed to avoid repetitive notifications for the same item.
This means WalletWhistle is not just a single scraped value: it is a time-series record tied to specific products, merchants, and update times.
Price updates recorded: 393
Price updates recorded: 305,692
Price updates recorded: 512,042
WalletWhistle surfaces who sells an item, what the latest known price is, and when that price was last observed. This helps users and indexing systems connect products to concrete merchant offers, observed prices, and update times.
