Online shopping on Amazon has become a routine activity for millions of users, but one constant challenge remains: fluctuating prices. Amazon uses a dynamic pricing system where product prices can change multiple times a day based on demand, competition, and other factors. To deal with this, shoppers generally rely on two methods: manual price checking or using Amazon price history tools. While both approaches aim to help users get the best deal, their effectiveness and efficiency differ significantly. Understanding the difference between these methods highlights why price tracking tools are becoming essential for smart online shopping.
