Independent Weekly Cannabis Price Index (consumer Prices) – Looking For Methodological Feedback

I’ve been building an independent weekly cannabis price index focused on consumer retail prices, not revenue or licensing data. Most cannabis market reporting tracks sales, licenses, or company performance. I couldn’t find a public dataset that consistently tracks what consumers actually pay week to week, so I started aggregating prices from public online retail listings and publishing a fixed-baseline index. High-level approach: Weekly index with a fixed baseline Category-level aggregation (CBD, THC, etc.) No merchant or product promotion Transparent, public methodology Intended as a complementary signal to macro market reports Methodology and latest index are public here: https://cannabisdealsus.com/cannabis-price-index/ https://cannabisdealsus.com/cannabis-price-index/methodology/ I’m mainly posting to get methodological feedback: Does this approach seem sound for tracking consumer price movement? Any obvious biases or gaps you’d expect from this type of data source? Anything you’d want clarified if you were citing something like this? Not selling anything and not looking for promotion — genuinely interested in critique.
