Probably everyone has been and knows what kind of store .... There is not a large selection of goods and it is located on pallets, queues at cash desks (since there are problems with paying by QR or card...I don't remember exactly anymore) Only if you know something specific in the name for a cheap price...since the goods in the bulk are "not expensive - with all the consequences"
There are many different products from household chemicals to groceries and prices are lower than in other stores. In terms of quality, there are very good products and there are not very good ones. But you can always choose something.
