Which price of each flavor do you show me?

The official one from the tax authority for tobacconists on the mainland and the Balearic Islands. In Profile → Preferences you can switch the zone to Ceuta and Melilla, which have different prices, and turn on “Hospitality prices” to see the one for bars, restaurants and vending machines, which carry a surcharge. It applies on the flavor page and in the shopping list; the value of your stash and collection is always calculated at mainland tobacconist price. The Canary Islands are not included: the tax authority doesn’t publish their prices in this list.
