Raised beds needn’t be totally filled with expensive compost. Other options exist. For example you could follow Hugelkultur techniques and put wood or other organic matter in the bottom. This fills out the bed and helps retain moisture.
Another option, the easiest for many of us, is to use home made compost in the bottom of the beds and top them with purchased compost. This significantly reduces the cost of filling the raised bed.
Alternatively, fill the bottom of deep beds with bales of straw and then top off with compost.
