Help!!!

I have built a couple larger projects, hope chest, media center and two end tables. I am spray painting the color I chose, Universal metallic carbon mist. I'm about halfway through, ran out of paint. and I cannot find that color anywhere in my town Home Depot and Lowe's both are out of it and it's super expensive online Lowe's was the best price I believe that I found is there any other places online or not that you recommend finding it? Or is there a different brand like(2x ultra) that has metallic carbon mist that I can special order or something?
