Vendor Trust Scorecard
Not all suppliers are equal. We score every vendor against five key trust criteria so you can make informed decisions about where to buy. Higher scores mean greater transparency and reliability.
COA Verified
30% weight
Payment Transparency
20% weight
Shipping Coverage
15% weight
Community Reviewed
20% weight
Active Listings
15% weight
Red Flags to Watch For
• No COA or only self-tested results
• Only crypto / untraceable payments
• No reviews or all 5-star (suspicious)
• Vague or no shipping info
• No customer support or contact info
• Prices drastically below market average
Our Scoring Methodology
Each vendor is evaluated against five criteria weighted by importance. COA verification carries the highest weight (30%) because third-party testing is the strongest indicator of product quality. Community reviews (20%) and payment transparency (20%) are weighted equally, while shipping coverage and listing activity each contribute 15%. Scores update in real-time as new data comes in.
No vendor can pay to improve their Trust Score. The full 0–100 rubric — explicit pass thresholds, data sources, red flags, and what we deliberately don't score — is published at /vendors/methodology.
