UnitDeal per-unit price comparison

Convert any e-commerce product to price per unit so bulk deals can't fool you

Problem

On Amazon and similar sites, the same daily item comes in dozens of pack sizes and only the total price is shown. Shoppers must mentally calculate cost per gram, per sheet, or per milliliter and often get fooled by fake bulk discounts.

Solution

A browser extension or lightweight app that scrapes quantity, unit, and price from product pages, normalizes to a common unit price, and overlays that alongside historical unit price trends.

Users

Households and small businesses that regularly stock up on consumables and office supplies online

MVP

Parse product pages on major marketplaces; detect unit and convert to normalized unit price; overlay unit price on listing pages; track historical unit prices for watched items

Revenue

Free basic comparison; paid tier for price alerts and historical trends via monthly or yearly subscription

Why now

Packaging and promotions are increasingly complex, and existing comparison tools only show total price; niche unit-price comparison is still open
