Methodology
Every figure on this page is computed from prices we collect directly from vendor sites, re-checked roughly every 6 hours and normalized to price per gram. The "current" column is the live average across every available product in that grade right now; the "May 2026" column is the average of the 3,378 price points we have banked, restricted to that month. The weekly trend sparkline shows each grade's recorded average over time; weeks with fewer than three recorded price points are dropped as low-confidence.
The All / Bulk / Smalls toggle re-cuts the same grades by size and sort. Bulk is any listing of a quarter-pound (112g) or larger; Smalls are the smaller buds vendors sell at a discount. These are subsets of each grade, not a separate split — a bulk indoor listing counts in both the Indoor and Bulk views — so the rows are a second lens on the same products rather than a partition. Bulk trends build up over time as we record the weight behind each price point.
One honest caveat: we record a historical price point when a product's best price changes (and when we first see the product), so monthly and weekly figures are averages of recorded price points rather than a continuous market index. They are best read as a directional signal of where each grade is moving, backed by real listed prices — not as a settlement-grade benchmark.
Grades follow the same taxonomy as the rest of the site: exotic (top-shelf designer cultivars), indoor, greenhouse (light-dep), outdoor (sungrown), and shake & trim. Click any grade to see every live listing behind its average, ranked cheapest per gram first.
