Where can I get a discontinued MAC lipstick?

I have a lipstick color that I love...apparently they discontinued it in May 2005. I called Estee Lauder (MAC's parent company) and they will still make discontinued items available via phone order for 2 years after they stop selling in stores--but I"ve missed the deadline! Is there any other way to find it? the lipstick color is called "smoove," by MAC.
