What is the enhancement in mind? How should it look and feel?

Add the ability to allow each individual package to be optionally limited to a list of worlds it is available in.

Please provide any additional information below.

Add a message to config.yml

RestrictedWorld: '&cYou cannot purchase that in this world.  You need to be in : %worlds'

Example config.yml package excerpt :

packages:
  ExamplePackage:
    price: 100
    description: This is an example package.
    ...
    RestrictToWorlds:
    - PvE
    - Creative

Change to code for handling purchase :

} else if (args[0].equalsIgnoreCase("purchase")) {
if (args.length != 2) {
    s.sendMessage(Prefix + InvalidArguments);
    return true;
} if (!DonationPoints.permission.has(s, "shop.purchase")) {
    s.sendMessage(Prefix + noPermissionMessage);
    return true;
}
String packName = args[1];
String caseSensitivePackName = packName;

// Resolve the supplied package name to the case sensitive equivalent from the config.
List<String> packages = new ArrayList<String>(plugin.getConfig().getConfigurationSection("packages").getKeys(false));
for (String packageName : packages)
{
    if (packageName.toLowerCase().equals(packName.toLowerCase()))
    {
        caseSensitivePackName = packageName;
        break;
    }
}
packName = caseSensitivePackName;

// If this is package is restricted to any worlds, then check the player is in one of the configured worlds
if (plugin.getConfig().contains("packages." + PackName + ".RestrictToWorlds"))
{
    Player p = (Player) s;
    String worldName = p.getLocation().getWorld().getName().toLowerCase();
    boolean worldFound = false;

    //s.sendMessage("player is in : " + worldName);

    List<String> worlds = plugin.getConfig().getStringList("packages." + PackName + ".RestrictToWorlds");
    for (String world : worlds)
    {
        //s.sendMessage("comparing : " + worldName + " and " + world.toLowerCase());
        if (worldName.equals(world.toLowerCase()))
        {
            worldFound = true;
            //s.sendMessage("matched.");
            break;
        }
    }

    if (worldFound == false)
    {
        s.sendMessage(Prefix + RestrictedWorldMessage.replace("%worlds", worlds.toString()));
        return true;
    }
}
