Reliable stores

In Finland, they switch to winter-summer time, because the time difference with Russia is 1-2 hours.
First of all, we take this into account when crossing the border, which closes at night.

Most stores start work at 9.00 or earlier (especially hypermarkets).

Closed stores are very differently, they can close quite early - at 16.00.
Large stores usually work until 19.00.

On weekends, it's usually a shorter day, on Sundays - a day off, except for the largest hypermarkets. It's better to aim at a large store, and find out the schedule through the site.

Prisma and Euromarket Work on weekdays from 7.00 to 21.00, on weekends to 18.00 or 19.00.

Before big holidays, the work time may increase.
