Just set the original world active again. This would require that the shop world retain a reference to the game world. Add a parameter the the constructor of the shop to accept a World object:

// for example
public Shop(World world)

and then use:

// in World subclass (game world)
Greenfoot.setWorld(new Shop(this));

// in Actor subclass
Greenfoot.setWorld(new Shop(getWorld()));

For the Shop world to retain the game world, it will need a World field:

private World gameWorld;

and it will need to be assigned the world in the shop constructor:

gameWorld = world;

To return to the current game, use:

// in shop World subclass
Greenfoot.setWorld(gameWorld);
