Duty free collect on return (Glasgow airport)

[LadyChilli]

Is it possible to buy duty free on the outward journey and collect it on your return to Glasgow? I seem to remember this being an option a few years ago but can't find anything online.

Due to exchange rates I feel like duty free is only a bargain if buying in sterling. Also the 100ml hand luggage rule makes it pointless to buy anything on the outward journey unless you intend to drink it all before you return. There's an amazing offer on Malfy gin at the moment and I want some!

I flew out of Edinburgh recently and this option was no longer available but they were able to put my purchase in a sealed bag which allowed me to take it on the plane in handluggage on the way home 10 days later, as long as the bag remained sealed
