Research by Ceneje has compared the Croatian and Slovenian ecommerce markets. The study found that both countries have similar proportions of online shoppers, with around 90% of internet users from both countries having gone online shopping at least once. However, there were differences in the frequency with which internet users in the two countries engage in online shopping. Whilst almost half of Croatian internet users shop online every month, this drops to just 37% in neighbouring Slovenia. Croatia also seems more open to cross-border ecommerce, with 40% of Croatians reporting that they usually buy from foreign websites. In Slovenia, however, this figure drops to under a fifth. Cash-on-delivery is the most popular payment option in both countries. However, whilst online credit card payments are another popular option in Slovenia, PayPal is more favoured in Croatia.
