We'd love to be able to start out with 100, but I think it's better to perfect a few, then expand the range after. It's easy to do once we have the money coming in, but along with buying a Kiosk the start-up costs will be high, so we need to cut costs where we're able, and getting all the ingredients for 100 different shakes will cost quite a lot of money. I can always suggest getting some more added on, just in case, but we're trying to avoid blending chocolate bars into them and making proper flavours for them.
We've already considered a reward card idea too, that will be something we look into after opening.
