just a lil addy to all above, in general, doesn't matter which area you live:
i sounds to me that some do still not know about the best price shopping, like some posters above recommended to purchase stuff at the little colmados, heck, those are the for sure by far most expensive places to shop, as they do their purchases at the bigger marketsand/or get the stuff delivered by middlesmen, small colmados do not even run their purchases in big quantities, so they do not even have the best prices on their purchases and add to that what they need to make as profit themselves.
sure it always depends where someone lives and how mobile someone is to do the best price purchases.
here on the far east, i purchase fruits at one single fruit stand in Veron, as they are the same family as the producers, so the stuff is always fresh and for fantastic prices. meat takes some time and testing to find a appropriate place, i have since years one butcher nearby where the Beef never failed, it did fail at every other place i tried in the area one day or an other. best bet for beef is for most the imported Beef at the big supermarkets, acceptable quality for good prices.
as for clothing and household stuff etc, for best prices, some mentioned the typical cheap Dollar Store styled shops at home, here you purchase your cheap clothing on specific Marketplaces, often even run by Haitians, in Higuey, the cheapest stores at home come out expensive to those marketplaces, but you need your time 9n the community to figure all such stuff out in your surroundings, it is not that someone can give you a map, mark some points and from there on you get everything for the best rates.
for example the small Flee Market we have here in the lil Town of Cabeza de Toro twice a week, they seel used clothes and new stuff of very good quality, on first approach a Gringo will be asked for 10 bucks for a nice shirt, once really living in the community the same shirt will cost 50 pesos and you can preorder what you want(color, fishing motives etc etc) and a week later they have it ready for you in their Truck.
as for prices to rent appartments and houses, that varies a lot from area to area of course.
here on the East(i can't comment on the rest of the Island for that) the last several years the rents went down very significantly, it is def a buyers and renters market, very bad for someone who bought some years ago and wanna sell now.
very good gated residencies offer 2 and 3 bedroom appartments fully furnished with good nice furnichures (often even the coffee cups, spoons, knifes etc etceverything in littchen included) for $400.- -$500.- per month. stand alone houses, for example 2 bedrooms, small garden, walled in with big gate for the carport for one Truck, furnished with no high quality furnichures, run for $400.- - $500.- per month. great big property houses, 3 1/2 bedrooms, 5 bathrooms, own pool, big garden, all walled in, carport for 2 big cars/trucks, unfurniched, run for $600-$700.- per month.
those properties bee a few years ago at least 50% more expensive to rent.
if you look on the more economic side of rentals, without the need of a gated community with a guard at the entrance 24/7, ten you find here 1-3 bedroom appartments from around RD$6.000.- -RD$10.000.- all around to live in the middle of the DR daily life.
that's all on the East which is considered costy compared to many other areas.
daily costs for the usual foodies etc really depend on what level you want to live.
if you lived at home on consumption of cheap local products(local beef, local fruits etc from your homecountry), then you can not compare those prices from home to the prices for the same products here, because here they are Imported stuff and for that more expensive than at home. you need to compare those items to the Local DR items available, and then the DR is sure not more expensive than your life was at home on the same level.
if you look on the prices for imported meats, imported frenchfries, imported apples etc etc in the DR, then you have to compare those prices to the rates for Imported Meats from Australia, french fries or potatoes from Europe, apples from Russia etc etc in the USA/Canada/where ever home is.
if you want the same products from your homecountry, then you need to keep in mind that they will be Imports here and tho they will cost more than back home.
