Its too bad you don't have a nursery near by to get good compost.
I haul 3 yards at a time in my truck for $39 a yard.
I can get sandy loam compost mix for $38 a yard.
Its nice to have a big old truck.
A cheap way to make your own Wall Mart compost is to mix sand and pine bark and then go out in your yard and get a Do Do pile left behind from your dog and you have Wall Mart compost.
Their manure is the same thing.
It says right on the bag NO LESS THAN 10% manure and I can guarantee you it is no more than 10%.
Years ago they sold pretty good stuff but not anymore.
I used to get bags of pure sheep manure from them.
