A fixed price is such a fixed price - it's always interesting to visit there. There are a lot of unnecessary but necessary little things: from fertilizer for orchids to cognac. By the way, for me, as a foreigner, it was surprising that the store sells alcohol, but at the same time you can buy it no earlier than 12 o'clock in the afternoon.
I go to a good store all the time and it's impossible to leave without buying. It's clean, the prices are set, the shelves are in order, the friendly attitude, they will help and prompt. On 10 out of 10!
