Anything that is anointed shouldn't be sold. For once it's anointed, it then belongs to God.
A pastor can sell them, before praying over them and anointing them. But once they are anointed, they are to be given freely.

Be careful, for there are many fake pastors, prophets and prophetess selling different kinds of anointed materials...

There is no Godly power, in any anointed materials being sold anywhere.
