Never say never. I would not rule out the possibility of a low end retailer getting the odd lot of high end coffee. Something to watch out for is called "High Mountain" coffee from Jamaica. It's often packaged to resemble Blue Mountain coffee with "from Jamaica" prominently displayed. It's good but not as good, or as expensive, as genuine Blue Mountain.
So this is another advantage of Dominican coffee. I don't think I've ever heard of the brand names being diluted or counterfeited. I reemmber buying some at an organic food shop in Paris for a party years ago. The cost was close to 20 euros for not quite one pound, but it was fresh and it brought back memories of the island.

However, we're drifting away from the OP. It's not available in DR
