E-commerce in Europe is becoming increasingly important in all market segments, and in most segments it already accounts for few or even several dozen percent of total trade. According to a report by E-commerce Europe, it has already left the US market behind in 2010. Year by year, the willingness to buy products, which until recently were not treated by many consumers as “online”, such as food products, is growing. Considering the above, the aim of the article is to determine the level of development of e-commerce in the European Union (EU-28). In the research procedure the literature and EUROSTAT data were used. The following research methods were used for data analysis: literature analysis, the Hellwig’s method and the threshold grouping method. The analysis was carried out in two periods, i.e. in 2014 and 2018, which allowed assessing the direction of changes in the surveyed.
