Where to buy pure cypress mulch?

Hi All,
I m not use to pure cypress mulch but my friends use this and they told me that if you want to buy online then its cheaper than other and i really want to use cypress mulch..

Don't you have to bake that stuff, too?

The cypress mulch from lowes is a cypress blend! be careful! I read the small print on it and it says it is blended with 'other natural woods' but it doesn't say what else is in there, so I wouldn't use it.
