How to build new supermarket in another town?

Tap the $ icon.

The prestige system is saving up, buying another supermarket in a different location and finally opening a new store with zero balance. Purchase Epic upgrades to permanently affect your game (this costs gems). When you move to a new location, you start out with nothing like the start of the game, albeit the surroundings will be a bit different. New locations will boost your profit (e.g. location two boosts your profit by 2x). Purchasing new locations cost a fortune (this amount scales with your current supermarket 'stage'). DO NOT SAVE UP MORE MONEY THAN WHAT IS REQUIRED TO PURCHASE THE NEW SUPERMARKET AS ALL OF YOUR EXTR MONEY WILL BE LOST ONCE YOU START.
