Get Instant Alerts When Prices Drop on Products You Want to Buy
Create an AI agent that tracks prices across multiple stores and notifies you the moment your target price is reached so you never miss a deal.
What You'll Build
Your AI agent will continuously monitor prices on items you want and alert you instantly when deals appear. It can:
- Track prices on any product across Amazon, eBay, Best Buy, Walmart, and other stores
- Monitor multiple variations like different sizes, colors, or configurations of the same product
- Compare prices automatically across stores to find the absolute lowest price
- Send instant notifications with direct purchase links when your target price is reached
Before You Start
- An Everna account (sign up at app.everna.io)
- Product URLs or names of items you want to track
- Target prices you're willing to pay
- Email, SMS, or Slack for notifications
How to Set It Up
Create Your Agent
Go to app.everna.io and click New Agent. Name it something like "Price Tracker" or "Deal Finder".
Define Your Price Tracking Rules
Tell your agent exactly what products to monitor, where to check, your target prices, and how to notify you. Here are three real world examples:
Example 1: Single Product Tracker
"Monitor this Sony WH-1000XM5 headphones on Amazon, Best Buy, and Walmart: [paste product URLs]. Check prices every 2 hours. My target price is $299 or lower. When any store reaches $299 or goes below, send me an instant SMS with the store name, current price, and direct buy link. Also track the price history in a Google Sheet so I can see trends."
Best for: Waiting for a specific item to drop to your budget
Example 2: Multi Product Shopping List
"I'm planning to buy these 5 items: [list products with target prices]. For each item, find it on Amazon, eBay, Best Buy, Walmart, and Newegg. Check all stores every 6 hours and compare prices. When ANY item hits its target price at ANY store, send me an email with product name, store, price, savings compared to typical price, and purchase link. Prioritize deals that save me 20% or more."
Best for: Shopping multiple items and want to buy when deals appear
Example 3: Category Monitoring
"Monitor the best selling gaming laptops with RTX 4070 GPUs on Amazon. Check the top 10 results every 4 hours. Look for any laptop that drops below $1,200 or has a lightning deal. When you find one, verify it has at least 16GB RAM and 512GB SSD, then send me a Slack notification with specs, price, discount percentage, review rating, and link. Only notify me about laptops with 4+ star ratings."
Best for: Watching a category instead of a specific product
Connect Required Tools
Enable the tools your agent needs to track prices and notify you:
- Web Browser - Visit store websites and check product pages
- Notifications - Send alerts via SMS, Email, or Slack
- Spreadsheet Access - Track price history in Google Sheets (optional)
No store accounts needed. Your agent browses publicly available prices.
Launch and Start Tracking
Click Create Agent to deploy. Your agent will start checking prices immediately. You'll get your first alert when any product hits your target price.
Check the logs to see current prices and verify tracking is working correctly.
Best Practices for Price Tracking
Set Realistic Target Prices
Research typical sale prices before setting targets. Use sites like CamelCamelCamel to see historical Amazon pricing. Target prices 10-30% below regular price are usually achievable during sales.
Check Multiple Stores
Different retailers often have different sale cycles. By monitoring 3-5 stores, you're much more likely to catch a deal quickly instead of waiting months for one specific store.
Balance Check Frequency with Urgency
For flash sales and lightning deals, check every 1-2 hours. For normal price drops, every 6-12 hours is fine. More frequent checks cost more but catch deals faster.
Include Stock Availability Checks
Tell your agent to only alert you if the item is actually in stock. Many price trackers notify about products that are unavailable or have long ship times.
Track Price History
Have your agent log all price checks to a spreadsheet. This helps you understand price patterns and adjust your target prices to be more realistic.
Act Fast on Alerts
When you get an alert, buy quickly. Popular deals can sell out in minutes. Use instant notifications like SMS for items with limited stock.
Common Issues and Solutions
Agent reports incorrect prices
Some stores show different prices based on location or account. Provide your agent with specific product page URLs instead of search results. Verify the correct item variant is being tracked.
Missing time sensitive deals
Increase check frequency to every 30-60 minutes for hot deals. Consider monitoring deal aggregator sites like Slickdeals or Reddit r/deals in addition to store pages directly.
Getting alerts for out of stock items
Update your agent instructions to include "only notify me if the item shows in stock and can be added to cart". Have it verify the buy button is active.
Never getting alerts (prices not reaching targets)
Your target prices may be unrealistic. Check historical data to see typical sale prices. Raise targets by 10-20% or wait for major sale events like Black Friday, Prime Day, etc.
