The Cohiba (Red Dot) cigars are made by General Cigar at their factory in Santiago. I do believe that some of them are sold at certain good cigar stores, but $63 a box seems like they are not the real ones, neither Cuban nor Dominican. And yes, they also fake Dominican brands.
Where will you be staying? If you are close to Santo Domingo go to the cigar store that is close to the Metro Station and see whether they carry the Dominican Cohibas, or try the cigar booth at the Nacional Supermarket.
In Santiago the Nacional Supermarket.
I can't think of any place else, exccept perhaps the cigar shop at Hotel Lina in Santo Domingo, or the Cigar Museum out by Higuey, run by one of the Kelner family.
sorry, but I cannot vouch for any other place.
Of course if you want to take the risk you can get some good Cubans on the way out of the Airport at the INTERDUTY Free Port shop...I think they are still in business.

I just re-read your post and saw that you mentioned Isabel La Cat?lica St.. those cigars were not the Dominican nor the Cuban cigars, they were fakes.
