The aim of the work is to investigate the perception of the effects of the introduction of the euro on consumers' food purchasing habits. An online survey was conducted among a sample of 215 respondents in the Republic of Croatia. The results of the survey show that respondents believe that their spending on food purchases increased after the introduction of the euro. More than half of the respondents are dissatisfied with the introduction of the euro, while a significant proportion are neutral. Half of respondents (48.9%) believe that inflation is caused by macroeconomic influences, while 43.7% blame the introduction of the euro and unjustified price rounding. The majority of respondents expect prices to change, but not to this extent, while a third of respondents are prepared for price increases. A high proportion of respondents believe that their standard of living has deteriorated due to rising prices. The frequency of food purchases has not changed for the majority of respondents since the introduction of the euro. According to consumers, the price increase was mainly reflected in food and non-alcoholic beverages, i.e. fresh fruit and vegetables, eggs, meat and dairy products, as well as catering services provided by restaurants, hotels and cafés. After the introduction of the euro, most respondents visit neighborhood grocery stores and specialist stores less frequently due to rising prices. 67% of respondents still convert prices into Croatian kuna to get an idea of the value of the product. Respondents use cards more often, which could indicate that they are unfamiliar with the new bills and coins and want to avoid rounding up and speed up payments. Using the chi-square test, it was found that women are more likely to convert prices into kuna and that they are more dissatisfied with the introduction of the euro. In addition, younger respondents under the age of 40 convert prices into kuna more often than respondents over 40.
