In June 2020, the volume of retail sales increased by 13.9% when compared with May 2020 as non-food and fuel stores continue their recovery from the sharp falls experienced since the start of the coronavirus (COVID-19) pandemic.
The two monthly increases in the volume of retail sales in May and June 2020 have brought total sales to a similar level as before the coronavirus pandemic; however, there is a mixed picture in different store types.
In June, while non-food stores and fuel sales show strong monthly growths in the volume of sales at 45.5% and 21.5% respectively, levels have still not recovered from the sharp falls experienced in March and April.
