How to sell item bundles?


I am planning to build a shop where you can buy bundles of items, but I was informed that when you place items into a chest and then try and place that chest into a shop the items fall out. Is there any way to get around this or a better solution?


Perhaps you could put something in a shop to validate said bundle and then have the bundle delivered by the mail service?


Or set up a place where one of your blockheads stay and sell said bundles personally. downsides would be loss of a blockhead and not able to sell the items 24/7


Those are the only problems, but it’s not so bad.
