Estonians made on average 16,000 purchases worth a total of 847,000 euros online each day in the first quarter of the year, around a fourth more than during the same period a year ago.
The number of purchases doubled over two years, the Bank of Estonia said.
Online shops based in the UK were the most popular sites, with Estonian shops only fifth on the list.
In other statistics, Estonians on average make 169 credit or debit card purchases per year, the third highest in EU after Finland (225) and the Netherlands (170). Latvians only make 75 bank card payments annually.
Estonians use bank cards seven times less frequently to withdraw cash compared to card payments. That ratio is a reverse from 2000 when cards were mostly used to withdraw money. The average sum withdrawn was 93 euros in the first quarter.
Around 1 million transactions are made in Estonia each day, totaling 371 million euros in value. The number of transactions has increased since the first quarter of 2014 (by 5 percent) but the total value decreased (by 14 percent). 63 percent of all transactions were made using a bank card.
