The location for non-motorists is not very convenient: at a distance from the final bus stop, you will also have to walk past the abandoned building. But the store itself is out of competition at prices, especially for non-food products.
It's dirty, but you don't expect anything else from a traffic light. Products and especially household chemicals are many times cheaper than anywhere else. There are Russian goods, and there is always buckwheat. For large purchases, that's the thing.
