Login and history
Amazon shows different prices to logged-in vs anonymous users. If you buy often and Amazon profiles you as a low-elasticity buyer (you'll buy anyway), you tend to see slightly higher prices than a new visitor.
Full transparency
How Glitchoo works
Amazon uses dynamic pricing that shows different prices to different users. On this page we explain step by step how it works, why prices on Glitchoo may differ from what you see, and what we do to be as transparent as possible.
Why Amazon prices aren't fixed
When you load an Amazon product page, the price shown isn't from a fixed catalog. It's calculated in real time by an algorithm that evaluates dozens of signals. Here are the main ones:
Geographic location
City, region and IP affect pricing: zones with higher logistics costs or different spending power may see price variations on the same product.
Device and browser
Mobile vs desktop, Apple vs Android, browser used — yes, really. Amazon tests different prices to optimize conversions across segments.
Time and seasonality
Evening shopping, weekends, proximity to events like Black Friday: every hour can have its own pricing. Available stock also plays a big role.
Continuous A/B tests
Amazon literally tries different prices on different users at the same moment to find the optimal price point. The same product can cost €16 to you and €17 to someone else simultaneously.
Personalized coupons
Amazon may show you auto-applied coupons or discounts based on your profile (cart abandoned, purchase frequency, Prime). Coupons other users don't see.
💡 It's not a bug and it's not a scam: it's Amazon's business model. It's been like this since 2000 and is perfectly legal. The difference between the price you see and the one we see on Glitchoo is usually €1-3 — rarely more.
How Glitchoo monitors prices
We want to be honest: we don't show you Amazon's personalized price, because we can't. We show you the "anonymous baseline" — what Amazon serves to a fresh visitor with no profile, no login.
- Step1
Automated anonymous monitoring
Glitchoo periodically checks Amazon's public product pages just like any visitor would. No login, no cookies, no history — we see the "clean" default price shown to everyone.
- Step2
Verification and parsing
For each product we extract current price, recommended price, discount, active coupons, rating, reviews. We save everything in DB and keep history for 90 days.
- Step3
Price error detection
Our algorithm flags any drop greater than 60% vs historical average as "price error". These products land on the front page because they usually last only hours.
- Step4
Trust Score 0-100
For every deal we compute a score that combines discount magnitude, product quality (rating + reviews), historical rarity and contextual bonuses. We don't push what our own algorithm doesn't promote.
What you can trust on Glitchoo
Directly verified prices
Every price is verified directly on Amazon's public page — never invented, never estimated. If we say €16, it's because Amazon shows €16 to an anonymous visitor at the same moment.
Transparent Trust Score
The algorithm is documented. You know exactly why a deal scores 78/100 and another 45/100. No magic, no arbitrary "editor's picks".
Real price history
90-day price history is based on our actual observations, not third-party data. You see the true price over time, not an extrapolation.
Frequently Asked Questions
Why does Amazon show €17 while Glitchoo says €16?+
You're probably logged in/Prime and Amazon profiles you as a less price-sensitive buyer. Try opening the same product in incognito: you'll often see the "anonymous" price we show. Difference is usually €1-3.
Is the Glitchoo price what I'll actually pay?+
Probably yes, but we can't guarantee it because it depends on your Amazon profile. The price we show is what a fresh anonymous visitor would see. If you have a heavy profile, you might see a few euros difference.
What happens when a price error ends?+
Price errors typically last 1-6 hours. When they end, the product returns to regular price. That's why we flag them immediately and recommend hurrying up when you see the "Price error" badge.
Why do I see different prices depending on the country?+
Amazon has separate catalogs for each country. The same product can have completely different ASINs, prices and availability on amazon.it vs amazon.de. Glitchoo monitors 6 marketplaces separately.
Can I buy through Glitchoo?+
No, Glitchoo doesn't sell anything. We redirect you to official Amazon pages with our affiliate tag. You buy directly on Amazon — no intermediaries, no Glitchoo cart. Our only revenue is the affiliate commission on your purchases.
Is Glitchoo affiliated with Amazon?+
We're enrolled in Amazon Associates (like thousands of other sites) but we're NOT sponsored or controlled by Amazon. Our mission is to give you the best tool to find deals, even if that means telling you "wait, don't buy now" when the deal isn't worth it.
