at baa airports its £28 per box and at dalaman it was about £17 per box on thomas cook flights its £24 per box,

we buy 4 boxes at airport going out 2 on the plane, 4 in dalaman on arrival and the same coming home, but ensure you take a ruck sack to put your you stuff you but at outbound airport and on flight into as your only allowed so much to take into turkey

good luck

Thanks Gregg!
