Why Price Tracking is Essential for Online Shoppers

E-commerce algorithms change product prices multiple times each day. Over 62% of online items in India reach their all-time lowest price on normal weekdays rather than heavily advertised holiday sales. A 90-day price tracker ensures you buy when prices hit rock bottom, not when advertising campaigns tell you to.

Online shopping pricing in India has become dynamic. Amazon India and Flipkart adjust millions of product prices round the clock using machine learning algorithms that track inventory levels, competitor price shifts, browser cookies, and purchasing velocity.

Because prices change so frequently, static MRP tags are meaningless. Price tracking tools provide full historical visibility by recording snapshots of product prices over 90 days and displaying clear trend lines.

How E-Commerce Price Fluctuation Cycles Work

  • Flash Deal Cycles: Items are temporarily reduced for 4 to 12 hours to trigger quick impulse conversions.
  • Pre-Sale Artificial Inflation: Sellers raise prices by 15% to 40% a week before major events (e.g. Great Indian Festival, Big Billion Days) to make festive discounts look larger.
  • Stock Clearance Drops: When newer product iterations arrive (e.g. iPhone 16 release), older versions experience steep permanent price dips.
  • Competitor Price Matching: When Flipkart drops the price of a television, Amazon's bots match or undercut that exact price within 30 minutes.
