See that is what is great about getting into a forum that has such knowledgeable members.

I get my sawdust for free. ($5 to load onto my truck)
I think the pellets are $5 a bag.
But I also know from picking my stalls and my paddocks daily that the amount of waste can increase rapidly.

Here in Central Pa, we have such varied weather.
Our summers are shorter than most.
Our winters tend to be cold longer.
We have humidity in the summer, but probably not as bad as the southern states.

I really appreciate the info that other members have posted here.
