We are currently expanding our product catalogue and price data. Some pages may respond more slowly than usual over the next few days.

How prices move across a whole category, a brand, or a brand within a category. Each index follows the month-to-month price change of every tracked part in it, starting at 100. An index level of 108 means prices are about 8% higher than at the start; 95 means about 5% lower.
