COVID-19 is a virus that appeared at the end of 2019 in China and soon spread around the world, which corresponds to the definition of a pandemic. The pandemic is thought to have affected the economy in three ways: by directly affecting production (supply), by creating market disruptions, and by financially affecting businesses and markets. Although the pandemic has negatively affected almost all sectors of the economy, online commerce has experienced growth and progress. Although online commerce grew sharply even before the pandemic began, mobility restrictions imposed with the aim of reducing infection resulted in the dominance of this form of commerce. For this reason, demands have been imposed on stores to quickly adapt and integrate digital technologies in retail and business, and supply chain factors, shortages and spikes in demand have contributed to the sharp rise in Internet prices. The aim of this paper was to review the literature on online commerce during the Covid-19 pandemic and to support the theory with examples from practice in the Republic of Croatia, for which the examples of Konzum, Glovo, Wolt and Annona were used.
