            System.out.println("Choose one of the following products");
            System.out.println("smiley");
            System.out.println("veggie strips");
            System.out.println("milk");
            String item1 = sc.nextLine();
            System.out.println("how many of these?");
            int qty1 = sc.nextInt();
            if (item1.equalsIgnoreCase("smiley")) {
                double cost1 = 30 * qty1;
                System.out.print("The total bill now is");
                System.out.println(cost1);

            }
            double t = qty2 * 20;
            double p = sc.nextDouble();
            if (item2.equalsIgnoreCase("milk")) {
                System.out.print("okay that costed you ");

                System.out.print("the total bill is ");
                System.out.println(cost1+t+p*40);
            }
            else if (item2.equalsIgnoreCase("veggie fingers")) {
                System.out.print("okay that costed you ");
