Yandex.Lavka service launches large darkstores of up to 500 sq. m. in Moscow districts with high population density. First of them will start working at the end of September. The area of the existing objects is 2,5-3 times less - 150-200 sq.m. on average. Large darkstores are necessary for Yandex.Lavka to increase assortment of supermarket items for express delivery up to 6000 items. That's twice as much as it is now.
