Non-chain retail grocery prices saw a monthly increase of 0.67% and a significant year-on-year rise of four percent in April, as reported by Evotor. This surge was primarily driven by price hikes in mayonnaise (4.6% monthly, 17% yearly), sausages, and wieners (three% monthly, four% yearly). Other products like cheese, vegetable oil, chocolates, and canned food experienced a two% monthly price increase. Prices for baked goods, buns, cookies, crackers, butter, and margarine also rose slightly, by one%. In contrast, several categories saw price decreases in brick-and-mortar stores, including sour cream, marshmallows, semi-finished meat products, cereals. Prices for water, tea, coffee, and gingerbread remained relatively stable. Evotor's product index, which measures prices across 187 product names from 47 key categories for traditional trade, was used to estimate these price trends.
