MySql conditional order by

I have this table (simplified):

CREATE TABLE `my_table` (
  `id` INT NOT NULL AUTO_INCREMENT ,
  `item_name` VARCHAR(45) NULL ,
  `price` DECIMAL(10,0) NULL ,
  PRIMARY KEY (`id`) )

I need to select all items from the table, ordered this way:
1. items with price > 0.00 first, ordered by price ASC
2. items with price = 0.00 last, ordered by id

I tried this:

    SELECT * 
    FROM my_table 
    WHERE 1  
    ORDER BY 
      CASE price WHEN !0.00 THEN price 
       ELSE id
      END 
    ASC

And i get results like

item_name | price
----------|-------
foo       | 150,00
bar       |   0,00
baz       | 500,00
hum       |   0,00

How do I build the query to have

item_name | price
----------|-------
foo       | 150,00
baz       | 500,00
bar       |   0,00
hum       |   0,00

Thank you for your time

This will do the trick..

 SELECT * 
    FROM my_table 
    WHERE 1  
    ORDER BY 
      CASE price WHEN 0 THEN 1
       ELSE -1
      END ASC, price asc, id asc
