Usually 100ml is the size I used to get. But I think one can get 500ml also.By "whole bottle" what size are you referring to? I was just in our TSC the other day looking for something else and saw it there with the chicken stuff. It was small, like a perfume bottle's worth (an ounce or two). I wasn't paying much attention but that little bottle was $40 or $50 something! Dang, I'm sorry to anyone who needs this stuff, and hope I never do!
