CartHappy is a free Chrome extension aimed at people who buy groceries online and want to stop manually checking weekly ads and coupon pages. Once installed, it sits alongside your normal shopping flow: when you open a retailer's product page it scans the page, looks for available discounts, and applies the ones that actually work before you check out. The extension also compares prices so you can see when switching stores or swapping an item would save money.
The headline feature is the 'Regular List' — a personal shopping assistant that remembers what you buy, hunts for the best prices across your retailers, and pre-fills carts for you to review and confirm. According to the product site, price comparisons draw on a catalogue of more than 12,000 stores, with direct in-page support on a core set of major US grocery chains and passive price inclusion for others.
A practical note on identity: hifrontstreet.com is the domain this listing originally pointed to, and it currently redirects to carthappy.com. The 'Front Street' buying and loyalty tracking product described in older directory data is no longer what this domain serves; CartHappy is an independent grocery savings tool and is not affiliated with the retailers it references.
