CLV71, sorry I didn't see this until I got your PM -- it's been a busy day and I just missed it.
Yes, I do mean the ones that you can use to heat your house, or burn in outdoor wood stoves. They're also made to use as horse bedding, but I think those are about a dollar a bag more expensive although they're the same thing.
I assume it's also true in other areas, but here they are definitely a seasonal item. Of course, we only have two months of winter, so that's a long time to keep stove fuel on the shelves when it's not needed. If I don't get all I need for the summer and fall by the middle to the end of February, I'm just out of luck. As it happens, I'm going this week to load up on enough to last me for a year.
I also assume that if you can find someone who supplies horse farms, that it's a year-round item for them. But there aren't any horses near me, so I don't really know.
