Not necessarily a thread jack, but despite the Penzey's tip, which I appreciated, 
when it was time for me to buy spices online, I actually searched guugle for granulated worcesteshire
sauce and came up with Firehouse Pantry Ltd out of Ohio.  Not a chain, kind of a mom and pop to hear
them tell it.  Might do a price comparison today if I get bored and update that info.  
But I was happy with my order, til I exploded a giant baggie of rub onto myself while mixing up
my various goodies.  That took the fun out of receiving the package.

Granulated Worcesteshire at FHP $8.19 lb, not avail at Penz 

Hungarian Paprika  $6.78 lb at FHP, $16 lb at Penz
Granulated roasted garlic $5 lb at FHP, $11.20 at Penz

That's 3 from my rub mix, and it seems that's enough!
