A lot of people who come to Gran Canaria stock up on perfume because the island has the lowest prices in Europe thanks to its excellent shops and low taxes. 

Cigarette prices in Gran Canaria are still amongst the cheapest in Europe and it is almost always cheaper to buy them in a supermarket or local shop than in the airport duty-free.

Airport duty-free shops go all out to entice you to buy booze, cigarettes, perfume, and chocolate. But on a low-tax island like Gran Canaria, is it worth waiting until the departure lounge to buy?
