PuffPricer's value is comparability: every THCA listing we show is reduced to the same unit so you can compare it head-to-head. Here's exactly how that works.
Where the data comes from
Automated collectors read each vendor's public product pages and refresh several times a day. We capture the product name, strain, weights offered, prices, and availability as the vendor publishes them. We don't receive private feeds and we don't edit a vendor's prices.
Normalizing to price per gram
Vendors price flower in many formats — an eighth (3.5g), a quarter (7g), an ounce (28g), a quarter-pound (112g), and bulk. We convert each weight to grams and compute price per gram, so a discounted eighth and a bulk ounce can be compared directly. Edibles are normalized to price per milligram of total cannabinoid instead.
What "best price" means
Listings are ranked cheapest price-per-gram first among in-stock products. Larger weights almost always win on a per-gram basis, so the best raw value tends to rise to the top — but the full price table is shown on each card so you can choose the weight that fits you.
Grades
- Exotic — top-shelf, highest-potency or premium genetics.
- Indoor — grown indoors under lights; consistent quality.
- Greenhouse / light-dep — greenhouse-grown; a middle tier on price.
- Outdoor — sun-grown; usually the lowest cost per gram.
- Shake / trim — loose flower material, flagged separately since it isn't a grade.
Limitations
Prices and availability can change between refreshes, and some discounts only apply at a vendor's checkout, so the figures here are a current snapshot — not a guarantee. Always confirm the price, stock, lab results, and shipping to your state on the vendor's own site before ordering. Spot something wrong? Tell us and we'll fix it.
