One of the ways I make moolah is to buy supplies cheaply on the surface and sell them to the sisters. It is very annoying to have to click a button over 70 times (140 if you include the "continue" button). A ‘Buy 10 supplies’ option would help a lot.
I also highly recommend a ‘sell 10 supplies’ to the sisters option too.
