"Here comes a perfectly valid argument: To start with, whoever is not a rare consumer of Herbal Essences shampoo is an occasional purchaser of Organix Hair shampoo. Now, everyone who is not a regular user of Cetaphil soap is however a rare consumer of TIGI shampoo and an occasional purchaser of Organix Hair shampoo. Moreover, nobody is neither a rare consumer of Herbal Essences shampoo nor a rare consumer of TIGI shampoo. It follows that whoever is not a rare consumer of Herbal Essences shampoo is a regular user of Cetaphil soap."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
