"In May, the increase in turnover was primarily influenced by enterprises engaged in the retail sale of automotive fuel, where turnover grew by 8% compared to May 2021," Johanna Pihlak, analyst at SE, said.
Sales of manufactured goods went up 3%, led by second-hand goods and turnover in non-store sales.
Also, there was a slightly smaller rise in the turnover of other non-specialized stores selling predominantly manufactured goods.
On a monthly basis, retail sales rose 6.5% in May, reversing from a 5.6% drop in April.
