Duty Free Shops
There are four main duty free providers at Prague airport (not including clothes shops etc):
Czech Airlines (CSA)
Normally the CSA shops sell all items and they specify special duty free sections depending on whether your final destination is EU or non-EU.
Travel Value
This shop has a "best of" selection in Terminal 1 but normally it splits it shops into "Perfume only" and "Alcohol/Tobacco". This year it was quite common to see a "buy 5 cartons of B&H cigarettes, get a 1L Becherovka for free" type deal.
Dufry
Basically the same as CSA shops but they have a little 50Kc discount if you are a regular.
Aelia
This is the first place you'll see if departing from Terminal 1 as its on the right after passport control. Biggest shop in the terminal with the best selection of all goods perfume/drink/tobacco/sweets etc.
