HOFA plugins can be resold, but you need to deactivate the licenses for the respective products beforehand.
Since the license transfer is done manually, an expense fee of €20 per product (up to max. €50 for multiple product) is charged.
Singular plugins and full bundles can be resold.
EDU products and only parts of bundles can NOT be resold (e.g. only the IQ-Series EQ from the IQ-Series Bundle).
