If your package is not showing up on your store, there are several things you should check:
Is the package enabled?
Packages can be enabled or disabled by changing the select box from within the package editor, make sure that it is enabled.
Is the category enabled?
A package lives within a category, if the category is not enabled, the package will now show up. You can enable the category by opening up the category editor and change the selector to "Enabled".
