There are several terminals in Dubai Airport:

• In Terminal 1, where Aeroflot flights arrive, Duty Free is on arrival (a small store). Mostly presented alcohol (cheaper than in Moscow Duty Free) and a small selection of perfumes. On departure from Dubai in 1 terminal Duty Free is a small shopping center, with departments of perfumery and cosmetics, alcohol, tobacco department, electronics, food department, souvenir, jewelry.

• In terminal 3, where only Emirates airlines fly, on arrival there is a small store Duty Free. Represented alcohol and perfumes. At the departure it is already a huge shopping center with departments: jewelry, alcohol, tobacco, perfumery and cosmetics, electronics, audio-video products, small boutiques of European companies, souvenir departments, pharmacy.

It is better not to linger on registration and get into Duty Free as soon as possible, spent 2 hours there will seem to you 5 minutes. :)
