Hi I am about to sail on Cunard and have purchased the beers wines and spirits option I understand the €13.50 max price but if I ordered say a large monkey 47 gin at $11.30 and a mixer at $3.40 this takes me over the max price allowed I assume then I pay for the whole drink minus the 20% discount? Or does the mixer not add to the $11.30 as it is a soft drink? Thus the price is in the inclusive range? Any advice would be greatly appreciated!!
