Even though one of their locations isn't that far from us, they won't deliver, so I can't tell you how prices compare.
If you are in the Knoxville area, you might want to check with Shamrock Organics on Ailor Ave (sort of down below where Alcoa Hwy meets I-40.) Shamrock's prices on pickup loads (by the scoop) were half what other local places wanted. (DH has built wall extenders for our pickup truck and takes a tarp so the mulch won't blow all over the highway on the way home.)
Another mulch is Monterrey Mushroom mulch, delivered by the very large dumptruck load. (There's a local phone # from Knoxville.)
I can't compare prices, but some offerings are similar.

I second Shamrocks. We have been getting their mulch for years. I believe we have used Monterrey in the past. I have not heard of the mulch company.
