About Price Data
Data Source
All price data is provided by the Hong Kong Consumer Council's Online Price Watch service. This is an official government-affiliated source that collects prices from major supermarkets in Hong Kong.

Why Some Stores Are Missing
Some popular stores like Don Don Donki, YATA, and HKTVmall are not included because they do not provide public price data APIs. The Consumer Council's data only covers stores that participate in their price monitoring program.
Data Freshness
Prices are updated regularly by the Consumer Council. This website caches data for 30 minutes to ensure fast loading while keeping information reasonably current.
