1. The Problem: Manual Price Checking Wastes Time
Before automation, tracking product prices across online stores was slow, repetitive, and error-prone:
Users had to manually
- Open multiple product pages
- Check prices repeatedly
- Record or remember previous prices
Often missed opportunities
- Price drops
- Limited-time deals
- No historical visibility into price trends
- Buying decisions were based on guesswork rather than data
Impact per user
- 30β60 minutes per day spent manually checking prices
- Missed savings on deals and discounts
- Decisions based on incomplete information
Core challenge: People want to buy at the right time but donβt want to constantly monitor prices themselves.
2. Results After Automation

- Price monitoring happens automatically every day
- Alerts are sent only when meaningful changes occur
