Not big. If you forgot something, you can buy it for your family and friends. Oil perfumes are heavy scents, I did not take magnets. You can pay with dollars. You need to present a ticket at the ticket office to sell what you choose
The terminal is small. Not to compare with the DXB terminal. It was built under the escpo2020. There are few passengers, so no queues. In addition to Dubai duty free (a stripped-down version), there are a couple of cafes (a poppy and a coffee shop). There is a large smoking room.
