Obukhov has the largest supermarket and the prices are reasonable. The supermarket also has a good Pick&Go mobile application, which allows you to immediately scan the purchased goods right at the counters or in your cart and not do it at the self-service checkout, the application allows you to pay from it by linking your card. Using the app saves a lot of time. I recommend that the rest of the supermarkets refine their applications to the Velmart level
