Santo Domingo fruit and vegetable markets

I did a youtube search but did not find much about fruit and vegetable markets in Santo Domingo.  Are there markets?  If so, are the prices marked or do you have to bargain?

I am sorry for the fruit and vegetable question.  I continue to search and I found a list of markets and lots of information about them.  Thanks again but I have answered my owned question.

There are markets but really the best prices are in trucks you  find parked on the side of the road!

Thank you Planner
