Why We Built an Independent Price Tracking Engine
Watersports equipment—windsurfing boards, carbon masts, wings, and hydrofoils—represents a significant financial investment. Unfortunately, deceptive retail practices such as “fake discounts” (inflating MSRP right before applying a markdown) are rampant in online retail.
We built SpiWindsurfing’s pricing engine to provide transparent, unbiased price intelligence so watermen and outdoor enthusiasts only buy at authentic historic lows.
The 4 Core Principles of Our Pricing Engine
1. 24/7 Automated Feed Scanning
Our ingestion workers monitor authorized retailer feeds and catalog APIs daily across North America and Europe, collecting price, shipping fees, and availability.
2. Moving Average & Historic Low Gate
Before any item is flagged as a deal on our site, our algorithm tests it against two criteria:
- 30-Day Moving Average: The current price must represent at least a 15% discount against the rolling median.
- Historic Record Check: We flag whether the price matches or beats the lowest recorded level in our database.
3. Editorial Gatekeeping (No Blind Automation)
An algorithm can spot numbers, but human domain knowledge ensures quality. Our editors review deal candidates to verify that the item is a full complete set (e.g., board includes fins, foil includes mast and fuselage) and from an authorized merchant.
4. Zero Pay-to-Play Rankings
Retailers cannot pay to have their offers ranked higher in our price comparison tables. Merchant listings are sorted strictly by total cost (item price plus shipping).
