Heard one trick that should work for every item with or without implemented command. What do I mean by this? If you have a plugin for custom item, Coke bottle and you can spawn one with /givecoke or have plugin for Lemonade bottle but you do not have spawn command or anything you can still give both items if spawn/skin the small bottle (the base items used in the plugins) and the proper Skin ID used for coke and lemonade... So if CompoundOptions can be updated to support SkinID for the sold items I guess we can sell custom items?
