# Amazon Price History Tracker

Amazon Price History Tracker is a product idea in the ecommerce category at difficulty 2/5, with moderate market demand and an estimated revenue potential of $300-1.5k/mo.

## Summary

Shoppers can't easily track price drops on Amazon items they're watching. This extension monitors prices and alerts users when items hit target prices, helping them make better buying decisions. Target: deal hunters and budget-conscious shoppers.

## Why this is interesting

CamelCamelCamel has existed since 2008 and Keepa dominates browser extensions for this exact use case, both with massive datasets and free tiers that are hard to compete with. The space got a second look when Amazon began suppressing price history visibility in its own UI around 2019-2021, but that gap is already saturated. At $300–1.5k/mo, the revenue ceiling reflects the reality that deal hunters are notoriously ad-averse and unlikely to pay for a premium tier when free alternatives exist, making monetization almost entirely dependent on affiliate commissions that Amazon can cut or restructure at any time. The single most likely failure mode is exactly that: Amazon affiliate program changes, API restrictions, or outright blocking of price-scraping behavior can kill the data pipeline overnight with no recourse.
