Prices fluctuate daily. A Bosch GSB 550 impact drill swung between ₹2,899 and ₹3,499 on Amazon India over the past quarter — a 20% difference for the exact same product. Flash sales, bank offers, no-cost EMI events, and seasonal markdowns mean the "best price" on any given day depends on which platform you're checking. Without a comparison tool, shoppers routinely overpay by 10–30%.

Listings aren't always identical. A product sold as "Stanley 10-piece screwdriver set" on one store may be bundled with a different case or warranty on another. DEXF normalises model numbers, matches SKUs, and shows you only genuine like-for-like comparisons — so you're not comparing a 12V cordless drill to an 18V one by mistake.

Stock, shipping and seller ratings matter. The lowest price is only useful if the seller actually ships to your pincode, keeps the item in stock, and has a credible return policy. DEXF filters out listings from low-rated sellers and surfaces in-stock inventory first, so you don't waste time on phantom deals.

Price history tells the truth. A "70% off" banner often inflates the MRP to make the discount look steeper than it is. Our 90-day price chart shows the real lowest price on record — so you know whether a "deal" is genuinely a deal or just clever marketing.
