How to read these figures
Figures compare two observation points (first vs latest) for 5,497 products with history, starting around Sep 2025. The average price change of tracked items and the equal-weighted basket change are not official government statistics - they treat every product equally and do not reflect household spending weights.
All 14 categories with products currently have a price baseline for comparison.
