For anyone who missed out on the Frontier whiskey deal of the day last week, it is £17.99 on the Amazon lightening deal and part of the £10 off £50 Amazon deal on beers wines and spirits! Code is SAVETENBWS.
Sooo potentially the equivalent of £14.40
£10 off £50 is 20% off essentially
£17.99 -20% = £14.39

Last I looked it was 24% claimed, gogogo!
