We honestly don't keep very good track of what we spend of food and laundry supplies....etc. However it's definitely not 50,000. Meat wise we only buy Chicken, usually local but once or twice a month we buy the big skinless, boneless brest packages from Pricesmart. We mainly live of fruit, vegetables, and red wine.
There are three of us plus 3 dogs and 3 cats.
That doesn't count eating out which may cost another RD$10-12,000 for maybe 6 times a month.
We eat a lot of chicken, pork, fish, cheese and ground beef. We'll eat imported beef maybe 3 times a month, a real treat.
Veggies come from local sources and Nacional, occasionally from PS (they have such large qualtities it can be difficult to store.)
Most of our meat at PS along with cleaning supplies. My mom likes her wine and that ain't cheap in the DR. Alida and I don't drink.
Heck, dog and cat food alone can be almost RD$4500.
