If I plan to run a lot of errands, I throw a small black lap-size fleece blanket in the back. It can be left folded neatly in the corner until you need it. Once unfolded, you can tuck it under and around plastic bags to keep them from sliding around so much, and you can save the area in the cargo net for heavier things. Also works great to wrap things that could snag the carpet.
