I bought Absolute Zero from Amco Wholesale but they only exist in PG. You can try contacting the maker of Absolute Zero, Envirotech, to see if they have any distributors in your area.
A word of warning though, I contacted them before I began using the product to see what they thought about it being added to an aquarium. Their recommendation was that it should not be used because their manufacturing process does not meet pharmaceutical grade standards and there is a possibility for contamination. On a related note the manufacturer of Mag Flake also does not recommend its product be used in this way. It would cost me roughly $4 more per pound to purchase pharmaceutical grade so I am willing to take that risk.
BTW have you ever noticed that there is a warning on the Q-Tips box not to insert them into your ear canal? Companies just dont want to be sued.
