The Kirkland branding is everywhere. I see it at the Australian stores.

None of the Anglosphere currencies would make this anything other than the price of a car anyway. This is absolutely just a collector’s item for those with more money than sense, never expected to be actually drunk

Kirkland Signature is Costco’s store brand.

There’s also a Kirkland near Montreal, so it could be Canada. But as it’s already been mentioned, it has nothing to do with location in this case.

I doubt this is in the US. The key indicator for me is the Napa valley wine beside it. Unless Costco does things very differently, imported bottles are always grouped into the same aisle. Given that I’d guess its outside the US.
