Answer
According to the figures cited, 30 eggs cost about 230 Uruguayan pesos, a kilogram of flour costs 59 pesos, and a kilogram of cheese from Colonia Helvética costs 779 pesos. Eggs feel noticeably more expensive than some other basic foods.
These figures are best treated as an illustrative basket, not a permanent price list. The price depends on the store, neighborhood, street market, brand, season, discount, and package size. The same product can differ in price and quality at a supermarket and a market.
To keep track of your budget, it is useful to compile your own basket of 20–30 regularly purchased items and record their prices once a month. This makes it clear where the cost of living is genuinely rising and where spending is changing because of the store you choose or your habits.
