How PonnoRadar Works
An open, transparent, and explainable methodology for tracking prices, calculating true checkout costs, exposing fake sales, and knowing exactly when to buy.
From Store Listing to Verified Intelligence
How our automated pipeline ingests raw retailer HTML, cleans noise, resolves canonical models, and computes real purchase value.
Universal URL Parsing & Canonical Resolution
When you paste a link or our crawlers sweep Star Tech, Ryans, TechLand, or Pickaboo, our dedicated store adapters dissect the listing. Rather than duplicating items across stores, our Canonical Matching Engine standardizes variations, cleans promotional suffixes, and links offers to a single source-of-truth product by SKU, model number, and GTIN.
Timestamped Observation & Cooldown Engine
Each price check records an immutable observation containing: timestamp, current price, currency, warranty configuration, seller rating, and stock state (In Stock, Out of Stock, or Pre-order). An intelligent cooldown algorithm filters redundant identical data while retaining micro-fluctuations to produce crystal-clear interactive charts.
Total Payable Cost & Bangladesh Realities
A sticker price of ৳25,000 does not mean you pay ৳25,000. In Bangladesh, delivery charges (Inside Dhaka ৳60 vs Outside Dhaka ৳120–৳150), Cash on Delivery (COD) surcharges (0.5%–1%), and payment gateway rebates (bKash/Nagad cashbacks or credit card discounts) drastically shift the final balance. We calculate the exact total payable figure.
Discount Score & Statistical Buy Guidance
We never take merchant strikethrough "MSRPs" at face value. Our proprietary 1.0 to 10.0 Discount Score compares the live price against 30-day, 90-day, and all-time actual transaction records. Shoppers receive honest recommendations: "Great Deal (Buy Now)", "Fair Market Price", or "Overpriced (Wait)".
৳1,800 lower than 90-day average
Recorded at ৳12,200 across 3 stores. Real 14% discount.
The True Cost Comparison Matrix
In many cases, Store A advertises a lower sticker price, but after adding inter-district courier shipping and Cash on Delivery charges, Store B (which offers free Dhaka pickup or 5% bKash rebate) ends up significantly cheaper.
| Cost Component | Store A (Seems Cheaper) | Store B (With PonnoRadar Insight) |
|---|---|---|
| Advertised Sticker Price | ৳24,500 | ৳24,900 |
| Shipping / Courier Delivery | +৳150 (Outside Dhaka) | ৳0 (Free Store Pickup / Promo) |
| Cash on Delivery (COD) Fee | +৳250 (1% Courier COD) | ৳0 (Prepaid via MFS) |
| Payment Method Cashback | None / Not supported | -৳1,245 (bKash 5% Instant Promo) |
| Total Money Out of Pocket | ৳24,900 | ৳23,655 You save ৳1,245 with Store B! |
PonnoRadar flags delivery discrepancies directly on the product comparison view so you are never surprised at checkout.
Test on Real ProductsThe 4-Pillar Catalog Accuracy Guarantee
Every product listed on PonnoRadar undergoes an algorithmic validation process yielding an audited Accuracy Score (Grade A+ to B).
1. Identity & Spec Matching
Cross-references manufacturer part numbers (MPN), GTIN/EAN, RAM/Storage variants, and GPU models to ensure an RTX 4060 Ti is never conflated with a standard RTX 4060.
2. Live Stock Integrity
Distinguishes real in-stock inventory from merchant phantom pages, expired links, and "Call for Price" placeholders so you never chase a deal that cannot be bought.
3. Cost Completeness
Audits known delivery rates, return periods, and official brand warranty coverage (e.g. 2-year official vs 7-day seller warranty) across all store listings.
4. Outlier & Glitch Rejection
Statistical anomaly filters instantly catch merchant data-entry errors (e.g., listing a ৳50,000 laptop for ৳500 by accident) before faulty data triggers false alerts.
How We Bust Fake 11.11 & Eid Discounts
Pre-sale price inflation is common in Bangladeshi e-commerce. Here is how PonnoRadar keeps you protected.
15 Days Before The "Mega Sale"
A merchant quietly raises the regular price of a gaming monitor from ৳22,000 to ৳27,500. Most shoppers don't notice the gradual creep.
The Flash Sale Day
The retailer slashes the price with bold marketing banners:
৳27,500 ৳23,500 (15% OFF!).
Unsuspecting shoppers think they are scoring an extraordinary bargain.
PonnoRadar Truth Alert
PonnoRadar checks historical data points and alerts the shopper: This "deal" is actually ৳1,500 more expensive than 3 weeks ago!
