Go to a different store!
i've been to every store on the island practically. there's only 300k people here, it's not a big place. nobody seems to keep in mind that i'm living in Madeira. this is an outpost in the middle of the atlantic ocean, directly west of mauritania. the majority of things from bovines here come from Azores, the remainder from the mainland. local production is pretty small scale, maybe a few thousand head of cattle on the whole island.
