Episode Details

A dairy farmer turned tech innovator, Will Duff, has launched CheckMyTrolley — a free app helping Kiwis slash grocery bills by comparing supermarket prices in real time. Inspired by viral social media posts exposing soaring food costs, Duff teamed up with developers to build a tool that lets users input their shopping lists and instantly see the cheapest options. With rising grocery prices now outpacing rent and power for some, apps like CheckMyTrolley, Grocer, and Grosave are empowering shoppers to save big — one user saved $100 in a month, others average 13% off per trip. Developers are even eyeing direct purchase features next, all while scraping publicly available data — no supermarket partnerships yet, but the mission is clear: help New Zealanders spend less, live better.
