Found the 370Z Portable Cargo Area Organizer for $18

4r3s

I have this and I like it a lot. The compartments have Velcro so you can make the area bigger if you need to. Each slot holds a 6 pack of beer very nicely. I like it because I can throw smaller items in the trunk and not have them sliding around all the time. Works really well for picking up dinner and some beer and then not have to worry about it in the passenger seat or sliding around in the trunk. I paid close to $60 for mine so $18 or even $30 is a steal in my opinion.
