About ChartBuy & Our Price Verification Methodology
ChartBuy (chartbuy.com) is an independent global price-tracking and deal-verification platform built to eliminate fake marketplace discounts, pre-sale price manipulation, and unverified seller risk.
1. Real 90-Day Price Baseline
Whenever a seller’s strikethrough MSRP exceeds the item’s recorded 90-day peak by more than 18%, ChartBuy flags it as an Inflated MSRP.
2. Strict Store & Order Vetting
We prioritize 4.5★+ products backed by strong shipment volume, 95%+ positive seller ratings, and AliExpress Choice warehouse fulfillment.
3. Anti-Bait SKU & Duty Math
Our ingestion guard rejects cheap accessory bait anomalies (<35% of 90d avg) and computes net customs thresholds after coupon stacking.
Editorial Independence & Affiliate Transparency
ChartBuy’s Buy-Timing Score (0–100) is computed purely from historical price proximity, real discount vs. 90-day average, MSRP honesty, and buyer review volume—never influenced by seller sponsorships. ChartBuy operates independently via the official AliExpress Portals API.
