What you do, is you first rent the suburbs. because of the free rent. Then you leave the price at $1.00 and wait until you have $400.00 and buy the Ice despenser (previously dont buy any upgrades) then you change your recipe to 5 lemons, 3 sugar and 3 ice cubes. All your customers will love your lemonade no matter what time of year it is or what the wheter is like.
