Free for the taking- as many truckloads of wood chips as you want. These are chips from a commercial tree company. Chips are from trees that were sent through the wood chipper and then dumped in large piles. Chips are not ground into tiny, fine mulch, but wood chipped size.
There are many dump truck sized piles available.
You may load yourself, or if scheduling in advance, assistance may be given in loading with a tractor/front end loader.
