There was a Costco in Bangkok. I think it was out Rama 2 way, too far away for me and a bad location in my opinion. I think it was operated by Tops ( the Central group) but closed down after being open for a short time possibly for a lack of people desiring to buy in bulk. I saw Kirkland products in my local Tops for awhile, I’ll have to check again to see if they still have some things on the shelves.
