What to buy in Gran Canaria

Cigarettes are as cheap as they come in Gran Canaria with a sleeve of 200 top brand ciggies like Marlboro and B&H costing less than 30 euros. A litre bottle of local Arehucas rum and brand spirits like Smirnoff vodka costs less than 10 euros in local supermarkets. Perfumes are also significantly cheaper than in most European countries, as are cameras and electronic goods, thanks to low VAT levels.   

Where to buy duty-free in Gran Canaria

Gran Canaria airport is rarely the best place to buy duty-free perfume, cigarettes and alcohol. Prices are almost always cheaper in local supermarkets like Hiperdino and Spar and in specialist shops like Fundgrube (for perfume). Buying local has the added advantage that you can pack your duty free in your suitcase and forget about it until you arrive home.
