An A-Z glossary of smart shopping terms on Amazon: from price error to Buy Box, from MSRP to coupon. Each entry with clear definition and links to in-depth content.
Navigating Amazon deals can feel like a maze of terms: price error, MSRP, Buy Box, dynamic pricing, coupon, Trust Score. This Amazon deal terms glossary gives you the essential definitions to become a smarter shopper and spot real bargains.
What does price error mean?
A price error (or price glitch) is a price listed on Amazon significantly lower than the correct one, often caused by human error or a system bug. It happens when a seller or Amazon itself enters a wrong price, for example a $1000 TV listed at $129.
These errors are short-lived: the platform fixes them in minutes or hours. Glitchoo currently has 723 active errors across its network, with an average discount of 67.1%, compared to 29.4% for normal promotions. To learn more, read the guide on how price errors work on Amazon.
Amazon's role in price errors
Amazon is not obligated to honor a mistaken price. According to its terms, it can cancel the order if the price is clearly wrong. However, it often honors the purchase, especially if the error is small or if the seller is Amazon itself.
What is the Trust Score?
The Trust Score is Glitchoo's proprietary indicator (0 to 100) that measures an offer's reliability. It combines:
- 90-day price history: checks if the discount is real or inflated.
- Seller reliability: third-party or Amazon?
- Coupon presence: legitimate additional discounts.
A high Trust Score (70+) means the offer has a high chance of being honored and maintaining the discounted price. Low scores signal cancellation risks.
Amazon deal terms glossary: main entries
ASIN
Amazon Standard Identification Number: a unique 10-character alphanumeric code identifying each product on Amazon. Use it to find the exact item, useful in watchlists and Glitchoo tracking.
Buy Box
The Buy Box is the yellow "Add to Cart" box on the product page. Whoever wins it (usually the seller with the best price and metrics) gets most sales. A price error often removes the seller from the Buy Box.
Counter-seasonal buying
Buying out-of-season items (e.g., swimsuits in January, scarves in July) when prices drop. It works well on Amazon because warehouses clear space. For instance, a Champion hoodie at −85% in summer is a classic counter-seasonal deal.
Coupon
A discount automatically applied at checkout, shown as a clippable box on the product page. Glitchoo displays it separately from the main discount percentage because coupons expire and can be removed without notice. Real coupons stack with the Amazon discount.
Dropshipping
A sales model where the seller keeps no inventory: when you order, the product ships directly from a third-party supplier (often Chinese). Prices can be low, but quality and delivery times vary. Be cautious with price errors on dropshipped items: Amazon may cancel them more easily.
Dynamic Pricing
Amazon's algorithm that adjusts prices in real-time based on demand, supply, competitor prices, and history. A product might cost $50 in the morning and $45 in the evening. Glitchoo tracks these fluctuations to alert you of historical lows.
EAN / UPC
European Article Number (13 digits) or Universal Product Code (12 digits for the US): barcodes identifying products internationally. Every Amazon product has one. Useful for finding identical items across different marketplaces.
Lightning Deal
A time-limited offer (usually 4-6 hours) with a fixed quantity. Amazon adds a timer and shows the percentage claimed. Not all are real bargains: some start from an inflated strikethrough price. Always check the price history.
MSRP / RRP
Manufacturer's Suggested Retail Price or Recommended Retail Price. It's the price the manufacturer suggests, often higher than the actual selling price. Sellers use it as a strikethrough price to show a fake discount. Glitchoo compares the strikethrough price with the 90-day history to expose false discounts.
Strikethrough price
The original price crossed out on Amazon, next to the discounted price. It can be real (the higher price it actually sold at) or inflated (to make the discount look bigger). Example: suppose a TV went from $599 to $399, but history shows it was $419 in March; the real discount is smaller than it seems.
Price Error

Trust Score

Comparison table: real prices vs fake discounts
| Element | Real price (honest discount) | Inflated price (fake discount) |

| Glitchoo Trust Score | High (70-100) | Low (0-40) |
| Seller | Amazon or reliable seller | Unknown third party or dropshipper |

Frequently Asked Questions
What is a price error on Amazon?
A price error is an anomalously low price, much lower than the correct one, published by mistake. Glitchoo monitors them and publishes them with a Trust Score. Amazon may cancel the order, but often honors the purchase.
How do I know if a discount is real?
Check the 90-day price history (available on Glitchoo) and the Trust Score. If the strikethrough price is higher than the recent historical max, it's likely a fake discount.
Is a coupon a guaranteed discount?
No, coupons expire and can be removed. Glitchoo displays them separately from the main discount percentage to avoid misleading.
What does ASIN mean and what's it for?
ASIN is Amazon's unique product code. It helps find the exact item across different marketplaces (e.g., same ASIN on Amazon US and UK).
Why does Glitchoo separate the Amazon discount from the coupon?
Because the Amazon discount is on the selling price, while the coupon is an additional temporary reduction. Adding them would give a false percentage.
Conclusion
Now you have all the tools to become a savvy deal hunter. Remember: don't trust the strikethrough price, check the history, and look at the Trust Score. Discover verified deals in real time and lock in your deal before it disappears. Prices change constantly — don't wait; these errors last hours, not days.
