where is the best place to buy duty free perfume?

[KatyMac]

At the airport
On the plane out,
In Barcelona (on 26th Dec)
In the Canaries or Madeira
In Malaga
At the airport in Barcelona
On the plane home

It's for my mum for Christmas (she will be getting it late)

only the Canaries are outside the EU for duty purposes, so that's the only place you can buy duty free.

airport shops and on-board shops bump up the prices to the same or more expensive than you would pay in the UK.

in short - don't bother.Look for special offers in the UK. Also a waste of aviation fuel lugging the stuff about.

Thank you

That is not necessarily true! Some perfume will be cheaper at the airport shop if it is a special promotion. On the plane choice is limited. I do not buy any old perfume, only exactly what I want and I check the price beforehand. For example it is difficult to buy Chanel Chance discounted in the UK but it is usually cheaper at the airport. However sites like allbeauty may have lesser brands for a better price than the airport. You could always buy at the airport and use that perfume all holiday. I often do that. If you are going from T5 Heathrow you have a mind boggling choice too so if you are not sure what you like, you can spend a fun hour trying them out.

Thanks my mum wants 100ml Beautiful so I am comparing prices just now

My SIL lives in Spain & reckons you can buy perfume cheaper in Malaga than at the airport or on the plane.
