I believe $1.00 each was the price for the small bottles. 200ml (7 ounces). I remember seeing that price on my last visit (2023).
When I'm on the island, I get the 500ml cans of Heineken. On arrival, I buy a case, and I don't really pay much attention to the price. It's what I want, and I'm on vacation, so I get what I want (within reason).
I'll report my experience after my next visit in May.
