Newspaper
When repotting plants, I always hated how the soil fell through the drainage holes. I then discovered placing cut a circle of old newspaper the same size as the bottom of your pot.

Shipping Peanuts
When I pot starter plants I use shipping peanuts in the bottom of the pot. It gives a nice drainage and extra room for roots.
