At Tabacalera Garc?a (Altadis)
You will only find their brands: Henry Clay, Dunhill, Montecristo, R&J, Santa Damiana, among others.
the Preferido is available only in Santiago. They run from 13.5K RD$ per box of 25 to about 9KRD$ per box, depending on size.
I would imagine that the large store there in La Romana hase many of the cigars you might like, I know they have all of the Fuente products, but at prioces that make me want to vomit!
Your best bet for La Aurora products, aside from a factory cisit is the Supermercado Nacional..I think.
