thanks Gringo Warrior for the
http://www.hothothot.com site.
I found both red and green there. A little pricey, $16.50 for 2 5oz bottles - that's including shipping, but that's ok, I finally get to try it! Just type in keyword "Marie Sharps".
Alot of other tasty sounding items there as well.
I have seen Melindas, but never tried it, but I will now. I love hot sauce! :p
