Amazon Price History: 30 vs 90 Days and What It Misses

TL;DR: Amazon's 30-day price history shows recent trends but misses longer patterns. Tools like Keepa offer 90+ days for free users, with full history for premium. But here's what all these tools miss: they only track future purchases. TaskMonkey scans your past 3 months of orders and automatically gets refunds on price drops you've already paid for.

Why Amazon Price History Matters

Amazon prices change constantly. According to Profitero's analysis, Amazon adjusts prices on millions of products up to 2.5 million times daily. That's roughly 8% of their entire catalog experiencing price fluctuations every single day.

Understanding price history helps you:

Identify whether a "deal" is actually a good price
Spot fake discounts during Prime Day or Black Friday
Time your purchases for predictable price dips
Avoid buying at artificial price peaks

But here's the problem: different tools show different time windows, and each has significant limitations. Let's break down what 30-day vs 90-day price history actually tells you, and more importantly, what it doesn't.

Amazon's Native Price History: The 30-Day Window

Amazon has been quietly rolling out a built-in "Price History" feature on product pages. According to 4seller's analysis, this feature appears beneath the list price on mobile and shows 30 to 90 days of price history.

You've probably seen Amazon's "Lowest Price in 30 Days" messaging. This badge means the current price is at or below the lowest featured offer price for that item in the past 30 days. While helpful, this window has serious limitations:

What 30 Days Shows You

Recent price volatility and short-term trends
Whether a current discount is genuine or inflated
Quick price changes around flash sales or deals

What 30 Days Misses

Seasonal pricing patterns (holiday drops, back-to-school sales)
Long-term price trajectory (is this product getting cheaper over time?)
Historical lows from previous major sales events
Artificial price inflation before big sales (common before Prime Day)

The 90-Day View: Better, But Still Limited

A 90-day price history window gives you significantly more context. You can see roughly a full quarter of pricing behavior, which typically includes at least one major sales event or seasonal shift.

What 90 Days Shows You

Pre-sale price inflation tactics
Recovery patterns after big sales
Monthly pricing cycles some sellers use
More accurate "lowest price" comparisons

However, 90 days still misses year-over-year patterns. A product that drops 40% every Black Friday won't show that pattern in a 90-day view if you're looking in March.

Third-Party Tool Comparison: How Much History Do You Actually Get?

Different price tracking tools offer vastly different history windows. Here's what you can expect:

Tool	Free History	Paid History	Update Frequency
Amazon Native	30-90 days	N/A	Real-time
Amazon Assistant	30 days	N/A	Real-time
Honey	30 days (default)	120 days max	Daily
Keepa (Free)	90 days	Full history	Every 15 min
CamelCamelCamel	Full history	N/A (always free)	Hourly
TaskMonkey	3 months of orders	Same	On-demand scan

Keepa: Power User's Choice

According to Keepa's official site, they track over 2 billion Amazon products across multiple marketplaces. Free users get 90 days of history, while the premium subscription (about $20/month) unlocks the full historical dataset dating back years.

Keepa's charts show multiple price lines: Amazon's direct price, third-party new offers, and used prices. This granularity is extremely valuable for understanding the full pricing picture. Learn more in our complete Keepa extension guide.

CamelCamelCamel: Free Full History

CamelCamelCamel has been tracking Amazon prices since 2008, and they offer complete price history for free. Their data can show you how a product has performed over multiple years, multiple Prime Days, and multiple holiday seasons.

The trade-off? CamelCamelCamel tracks about 6 million products compared to Keepa's 4.5+ billion. If you're looking at a niche or newer product, Keepa might have data where CamelCamelCamel doesn't. For more details, see our Keepa vs CamelCamelCamel vs Honey comparison.

The Fundamental Problem: All These Tools Look Forward

Here's what every price history tool on the market misses: they're designed to help you buy smarter in the future, not recover money on purchases you've already made.

Think about your Amazon order history. How many items did you buy in the last three months? Now consider that Amazon changes prices constantly. Statistically, many of those items have dropped in price since you paid.

The Hidden Refund Opportunity

Amazon doesn't officially advertise a price adjustment policy. As Consumer Reports notes, you typically need to ask customer service directly. And while Amazon ended its formal price drop refund policy, agents can still issue courtesy credits on a case-by-case basis.

The problem? Who has time to:

Go through every order from the last 3 months
Check current prices against what you paid
Calculate the difference
Contact customer service for each eligible item
Politely negotiate a refund

Most people don't. That's money left on the table.

TaskMonkey: Scanning Your Past, Not Just Your Future

This is where TaskMonkey takes a fundamentally different approach. Instead of tracking prices for items you might buy someday, we scan items you've already purchased.

Here's how it works:

Install the free Chrome extension
Click "Start Saving Now"
TaskMonkey automatically scans your last 3 months of Amazon orders
We compare what you paid vs. current prices
For any price drops, AI automatically contacts Amazon customer service
Credits and refunds go directly to your Amazon account

The 3-month window isn't arbitrary. It aligns with Amazon's return window policies and the timeframe where courtesy credits are most likely to be granted. We've successfully processed thousands of refund requests using this approach.

When to Use Each Tool

The smartest strategy combines multiple approaches:

For Future Purchases

Use CamelCamelCamel for free, long-term price history
Use Keepa for more detailed charts and faster updates
Check Amazon's native 30-day low badge for quick validation

For Past Purchases

Use TaskMonkey to scan your order history
Let AI handle the negotiation automatically
Collect refunds on items you've already bought

These tools complement each other. Price trackers help you pay less upfront. TaskMonkey helps you recover money after the fact.

Real Numbers: What 3 Months of Orders Typically Reveals

Based on our user data, the average Amazon customer who scans their 3-month order history discovers:

5-15 items with meaningful price drops
$50-200+ in potential recoverable difference
90%+ success rate when politely requesting courtesy credits

The key phrase is "courtesy credits." Amazon's customer service has discretion to issue these, and they frequently do when approached correctly. TaskMonkey's AI is trained to make these requests in a polite, effective manner that maximizes approval rates.

Frequently Asked Questions

Is 30 days enough price history to spot fake discounts?

It depends. For everyday purchases, 30 days can catch recent inflation. But for big sales like Prime Day or Black Friday, sellers often raise prices 60-90 days in advance. A 30-day view won't catch that. For more on spotting fake discounts, see our guide on verifying deals with price trackers.

Why doesn't Amazon show longer price history?

Amazon benefits from urgency. Showing that an item was $20 cheaper last month doesn't encourage you to buy now. Their 30-day window is just enough to satisfy EU transparency requirements while keeping historical context limited.

Can I request a price adjustment on any Amazon purchase?

You can request on any item, but success varies. Items purchased within the last 7-30 days have the highest success rate. Beyond that, courtesy credits become less common but still possible, especially with polite, persistent requests.

How is TaskMonkey different from setting price alerts?

Price alerts tell you when something drops. TaskMonkey works on items you've already bought. If you purchased a TV last month and it dropped $80 today, a price alert does nothing for you. TaskMonkey would detect that drop and try to get your money back.

The Bottom Line

Understanding Amazon's price history windows is valuable, but don't get lost in the data. The real question isn't "what will this cost in the future?" but "am I leaving money on the table from purchases I've already made?"

For forward-looking research, CamelCamelCamel and Keepa remain excellent tools. But for actually recovering money, you need something that looks backward at your order history, not forward at hypothetical purchases.

TaskMonkey scans 3 months of your Amazon orders, compares prices, and uses AI to request refunds automatically. We only charge when we successfully get money back for you, 20% of what we recover. If we don't save you anything, you pay nothing.

Stop leaving money on the table. Your past purchases deserve attention too.
