We had a 50% off entire store sale and we still had people asking if certain items were included or if this applies to international people.

That is a perfectly reasonable question. Stores always have exceptions, whether it be "things that require special shipping" or "alcohol and dairy products" or "products that are already reduced" or ... et cetera. And sometimes it's taken for granted that the customer already understands these exceptions.

Better to have a customer ask about something you think is obvious than to have them make assumptions about something they think is obvious.
