Supermarket prices showed a slight decline in September compared to August, with a number of products, however, continuing their upward trend, burdening the household basket.
According to the monthly survey of the Institute for Research Institute of Retail Consumer Goods (IELKA) exclusively in the channel of large supermarket chains, inflation in supermarket chains was around +0.61% in September 2025 compared to September 2024, with a tendency of gradual decline to lower levels compared to the previous 4 months.

The categories with the biggest price drops
The biggest price drops in September 2025 compared to the corresponding month last year were recorded in the categories:

Detergents and cleaning supplies: -5.40%
Grocery foods: -5.18%
Pet food & supplies: -3.21%
Disposable items, household items: -3.18%
As pointed out by IELKA, the decreases recorded were a result of both the normalization of the market and the decrease in producer prices for certain products. The largest decreases were recorded in fresh fruits and vegetables (the decrease comes from the vegetable category which has been favored by the weather conditions recently), in detergents and cleaning supplies and in grocery foods (due to the de-escalation of the price of olive oil).
