So the plugin allows you to set an expiration date on the packages. Is it possible for a user to have multiple packages? So let's say I buy a package with 1 post with a 1 year expiration. Then in 6 months I buy another package for 1 post. Then I would have 1 package that expires in 6 months and 1 package that expires in a year.
Deduct by first to expire? I just don't want someone to purchase a package that expires in a year, and on month 11 they buy another package and it resets the expiration on the credits that are about to expire.
