The Supermarket, I find, generally more expensive than the local colmados for the basics. Bread , I buy packets of Pan Agua at 30 ps, 10 rolls. Most bread otherwise I don't buy because the sugar they put in it makes such a funny taste. Rice around 20ps a pound. chicken around 40ps a pound. We don't eat out much but you can have a one plate lunch fot 100ps or a typical Dominican meal of rice, beans and meat or fish, and salad for up to 250ps. A glass of juice varies from 20 to 60ps and a coffee from 4ps to 40ps. i hope this helps.
