add 24 more bars
Select a candy bar by clicking on the green add to box button under each candy bar. If you want more than one of that candy bar, click the button that many times. As soon as you add one candy bar to your box, you will begin to see your box fill up above.
To remove a candy bar from your box, use the blue x located beside the candy bar name in the box filler. You must choose 24 candy bars. Once you have reached 24, you click the order button. You have now filled up one box of 24 of your favorite candy bars. If you want to fill another box up, you must repeat the process.
