How do you decide what's cheapest in Petaluma?

Every price is divided by the package size published on the menu — per gram for flower, carts and concentrates, per 100mg of THC for edibles. Items whose size isn't published are left out rather than estimated, so a cheap-looking half gram can't beat a genuinely cheap full gram.

How often do these Petaluma prices update?

Menus are re-read on a rolling schedule and these lists are rebuilt nightly. Each row shows when we last saw that listing. Confirm with the store before you travel.
