Yesterprice puts 53 everyday prices on a timeline

Field notes

Visitors can browse prices by aisle and sort items by the largest rise or fall from a year earlier; the visible controls include “Rose most” and “Fell most.” The egg example distinguishes its listed price from an inflation-adjusted figure, and the page describes the plotted line as monthly historical data. It also links to separate “Overpaying?” and “Pay less” sections, though the excerpt does not show how those checks work.
