Why Most People Overpay (And How to Stop)
You buy something online. Three days later, the price drops by 20%. Frustrating.
Or you wait too long for a discount and miss it completely.
Online stores change prices constantly, sometimes multiple times a day. You can't keep refreshing product pages.
A price drop tracker fixes this. It watches prices, logs history, and alerts you when your target hits.
Here's how to build one.
Create a Smart Wishlist
Start with intention, not with tools. Open a Google Sheet, Notion database, or Airtable base and create a small table with these columns:
Product name
Product URL
Current price (in your preferred currency)
Target price you are willing to pay
Start with intention. Build your smart wishlist in minutes using a simple spreadsheet.
Limit this list to things you genuinely plan to buy, such as a laptop, a course, or a specific gadget you have been considering for weeks. This becomes your smart wishlist rather than a random collection of “nice to have” items.
Once the list is ready, you can connect it to automation tools like n8n, Zapier, or a simple script to pull the current price for each URL once or twice a day. For sites like Amazon and eBay, price APIs and structured page data make it easier to extract the latest price reliably.
Log and Visualize Price History
See price patterns emerge. Historical data turns guesswork into strategy.
Each time your automation runs, store the current price in a “Price History” sheet or table with a timestamp. Over time, this creates a historical log that shows you how the price moves instead of just what it is today.
You can then use tools like Google Data Studio, built‑in charts in Sheets, or chart integrations in Notion and Airtable to plot this data. A simple line chart will quickly reveal patterns such as regular weekend dips, end‑of‑month discounts, or occasional deep sales. That turns your decision from “this looks cheaper” into “this is close to the lowest price seen in the last 30 days.”

Set Alerts for Your Target Price
Once you have data flowing, the real power comes from alerts. In your automation workflow, add a rule that checks whether the current price is less than or equal to your target price. When that condition is met, trigger a notification through email, Telegram, Slack, or any channel you check regularly.
A simple rule looks like this:
If current price ≤ target price → send alert with product name, current price, and link.
This means you no longer have to babysit product pages. You only hear from your system when the numbers match what you already decided you are willing to pay.
Add a Wait‑List to Prevent Impulse Buying
A discount alone is not a reason to buy. To avoid emotional purchases, introduce a wait‑list step even after the alert arrives. When you receive a price drop notification, add the product to a “Wait‑List” view with a review date, such as 3 or 7 days from now.
You can automate this with your database:
On alert, create a wait‑list entry with “Added on” and “Review after” dates
Use reminders or scheduled emails to nudge you when it is time to review
If you still want the item after the wait period, that is a strong signal it is a considered choice. If your interest fades, you simply archive it and keep your money for something that matters more.
Tools and Setup Flow
The complete toolkit. Simple automation that runs quietly in the background.
Here is a quick look at the core tools and how they fit together so the whole system is easy to imagine.
Core tools:
Google Sheets or Airtable as your central database
n8n, Zapier, or Make to run scheduled workflows
Price APIs or scraping logic to read prices from Amazon, eBay, or other stores
Email, Telegram, or Slack for notifications
Basic setup flow:
Add 3–5 products with URL, current price, and target price into your sheet or database.
Schedule an automation to fetch prices every day and append them to your history log.
Check each new price against your target and send an alert when the condition is met.
On alert, add the item to a wait‑list with a review date instead of buying instantly.
This small stack is enough to move you from reactive, emotional shopping to a calm, system‑driven approach that respects both your time and your budget.
