No way of saving the actual cost of a pack of cigarettes (i.e., I pay $23.90 in NZ for a pack). Not $10 as is the default. It lets you change the amount in the box, but doesn't save and always reverts back to default (there's no 'save settings' button). Kind of pointless if you're seeking to see how much you've saved. Essentially just wasted 20 mins of my time trying to figure it out.
