"Here comes a perfectly valid argument: First of all, everyone who is a loyal buyer of Herbal Essences shampoo is also an infrequent user of Caswell-Massey soap and a loyal buyer of Matrix shampoo. Next, Christian is not an infrequent user of Caswell-Massey soap or not a loyal buyer of Matrix shampoo. So, necessarily, Christian is not a loyal buyer of Herbal Essences shampoo."
Is the argument, given the explicitly stated premises, deductively valid or invalid?
Options:
- valid 
- invalid
