Get more life out of your sanding paper. After you've used an abrasive a few times, debris will become embedded in the tiny grit particles. This may reduce the effectiveness of the abrasive, but not necessarily mean that you need to replace it. There is a "abrasive eraser" available that will work to remove the particles and restore sanding power back to your sanding sheets, belts, disks, or drums.
A problem for those in northern climates is the constant hassle of moving tools from garage to basement in the fall and back again in spring. Newer roll-away storage chests, project centers, utility carts, and wheeled tool boxes provide portable storage to make the job easy. Rolling tool carts with extendable handles like carry-on luggage also let you divide tools according to the project and wheel right to the job.
