If you are buying just for yourself, expect to pay about US$ 50-70 per week. There is a new supermarket in La Romana, "Jumbo", little more than a yearold, it has just about everything you need. The store is modern, set up like in the states with many isles, food counters, cold and frozen food displays. The prices are above the colmado prices, however, you have more selection, one stop shopping, without having to travel over all God's creation to find what you need. It is located about 1-2 km west from the entrance to Casa de Campo and 1 km south from the park in the city center. The store also sell other wares, to include clothing, appliances, and novelties.
